CROSS-REFERENCE TO RELATED APPLICATIONS The present application is a continuation of International Application No. PCT/CN2024/102010, filed on Jun. 27, 2024, which claims priority to Chinese Patent Application No. 202310919041.X, filed on Jul. 25, 2023. The disclosures of the aforementioned application are hereby incorporated by reference in their entireties. TECHNICAL FIELD The present application relates to the field of vehicles technologies, and in particular, to a vehicle control method, a device, a vehicle and a non-transitory storage medium. BACKGROUND At present, with global resources being increasing scarce and environmental pollution being becoming more and more severe, environmental protection has increasingly become a topic concerned across various industries, and an automotive industry is no exception. Domestic and international automotive industries and their component developers are increasingly paying attention to whether there will be a fuel that may both protect environment and save resources applied toa vehicle. Therefore, a hydrogen fuel cell, as a clean, efficient, and pollution-free electrochemical power generation device, has attracted widespread attention both domestically and internationally. At the same time, a hydrogen fuel cell vehicle has become a mainstream development trend in the development of the current automotive industry. Consequently, safety and economy of a fuel cell vehicle have become widely concerned topics among various automotive enterprises. Currently, there is a requirement for purging a fuel cell for the fuel cell vehicle, and occasionally, it is necessary to upgrade an over-the-air technology (OTA). Therefore, there may be a situation where a functional conflict occurs between a purging function and an OTA upgrade function. Consequently, how to avoid the functional conflict between the OTA upgrade function and the purging function has become a technical problem that urgently needs to be solved. SUMMARY The present application provides a method and a device for vehicle control, a vehicle, and a non-transitory storage medium. The method is capable of avoiding a functional conflict between an OTA upgrade function and a purging function. In a first aspect, the present application provides the method for the vehicle control. The method includes: during a purging process of a fuel cell of a vehicle, when an over-the-air technology (OTA) upgrade request is received, executing an OTA upgrade process after the purging process is completed; and in a case that the vehicle is in an OTA upgrade mode, when a purging request for the fuel cell is received, performing the purging process of the fuel cell after the OTA upgrade process of is completed. In the above technical solution, during the purging process of the fuel cell of the vehicle, when the OTA upgrade request is received, the OTA upgrade request will not be immediately responded to. Instead, the OTA update process will be executed after the purging process is completed. In the case that the vehicle is in the OTA upgrade mode, when the purging request for the fuel cell is received, the purging request will not be immediately responded to. Instead, the purging process will be performed on the fuel cell after the OTA upgrade process is completed. By setting an execution logic between the OTA upgrade function and the purging function, it is beneficial to avoid the functional conflict between the OTA upgrade function and the purging function, thereby improving rationality of a vehicle control logic, and thus ensuring that the OTA upgrade process and the purging process are smoothly executed. In a possible implementation, the when the OTA upgrade request is received, executing the OTA upgrade process after the purging process is completed includes: when the OTA upgrade request is a request to upgrade a high voltage component, controlling a vehicle state to maintain a high-voltage state after the purging process is completed to upgrade the high-voltage component in the high-voltage state; and when the OTA upgrade request is a request to upgrade a low-voltage component, controlling the vehicle state to maintain a low-voltage state after the purging process is completed to upgrade the low-voltage component in the low-voltage state. In a possible implementation, when the OTA upgrade request is the request to upgrade the high-voltage component, the method also includes: determining the vehicle state; and controlling the vehicle to maintain a first high-voltage state in a case that the vehicle state is the first high-voltage state, where, the vehicle is not drivable in the first high-voltage state; and switching a second high-voltage state to the first high-voltage state in a case that the vehicle state is the second high-voltage state, where, the vehicle is drivable in the second high-voltage state; and the upgrading the high-voltage component in the high-voltage state includes: upgrading the high-voltage component in the first
