Description

BACKGROUND Technical Field The present invention relates to a display control device for a vehicle, a display system for a vehicle, a display control method for a vehicle, and a non-transitory storage medium. Related Art Japanese Patent Application Laid-Open (JP-A) No. 2019-119262 discloses a display device that, in a vehicle capable of running in a plural number of driving modes, displays an image giving notice of a change in driving mode of the vehicle in a display region to the front of a driver seat. Furthermore, US 2019/0263263 Al discloses a display control apparatus. A configuration is possible in which, when a vehicle occupant performs a driving operation during autonomous driving, driving operations by the vehicle occupant are given priority. In this configuration, when a vehicle occupant unintentionally performs a driving operation intervention (an override operation) during autonomous driving, some driving operations may be transferred to the vehicle occupant while the vehicle occupant is not ready. SUMMARY The present invention provides a vehicle display control device, a vehicle display system, a vehicle display control method and a non-transitory storage medium that may inform a vehicle occupant of a driving operation intervention during autonomous driving. A vehicle display control device according to a first aspect of the present invention includes: a driving mode acquisition section that acquires information on which of a manual driving mode or an autonomous driving mode is a driving mode, a vehicle running via driving operations by a vehicle occupant in the manual driving mode, and the vehicle running independent of driving operations by the vehicle occupant in the autonomous driving mode; an operation intervention detection section that, in a case in which the driving mode acquired by the driving mode acquisition section is the autonomous driving mode, detects a driving operation intervention by the vehicle occupant; and a display control section that displays vicinity information of the vehicle at a display unit provided at a vehicle cabin at least in a case in which the driving mode acquired by the driving mode acquisition section is the autonomous driving mode, wherein, in a case in which a driving operation intervention is detected by the operation intervention detection section, the display control section changes background information of the vicinity information and displays the background information at the display unit. In the vehicle display control device according to the first aspect of the present invention, the driving mode acquisition section acquires the driving mode of the vehicle. This driving mode acquisition section acquires information on which driving mode the vehicle is in, of a manual driving mode in which the vehicle runs via driving operations by a vehicle occupant and an autonomous driving mode in which the vehicle runs independent of driving operations by the vehicle occupant. At least in a case in which the driving mode acquired by the driving mode acquisition section is the autonomous driving mode, the display control section displays vicinity information of the vehicle at the display unit provided in the cabin. Therefore, in the autonomous driving mode, the vehicle occupant may check vicinity information of the vehicle by looking at the display unit. The operation intervention detection section detects a driving operation intervention by the vehicle occupant in the autonomous driving mode. In a case in which a driving operation intervention is detected by the operation intervention detection section, the display control section changes background information of the vicinity information of the vehicle that is displayed at the display unit. Therefore, if the vehicle occupant unintentionally performs a driving operation during running in the autonomous driving mode, because a background of the display unit changes, the driving operation intervention may be reported to the vehicle occupant visually. Thus, disturbance of the comfort of another vehicle occupant may be suppressed compared to a configuration that frequently reports to the vehicle occupant by voice messages. In a vehicle display control device according to a second aspect of the present invention, the operation intervention detection section may detect, as a driving operation intervention, at least one of a steering operation by the vehicle occupant or an accelerator operation by the vehicle occupant. In the vehicle display control device according to the second aspect of the present invention, the background of the display unit changes in a case in which at least of a steering operation of an accelerator operation is performed by the vehicle occupant. Therefore, the vehicle occupant may understand that one or both of the steering wheel and the accelerator has been operated. In a vehicle display control device according to a third aspect of the present invention, the display control section may displ
