Sure. But how the firmware process functions matters. There's a world of difference between remotely initated OTA over the interent vs flashing it locally via a USB drive or microSD card. You know like PC motherboards keep working for decades now. They are effectively read-only under normal use and need to have a certain reboot sequence (BIOS/UEFI fw admin) to unlock flashing. Or maybe even load firmware from a preinstalled SD card which makes swapping easy. Or if you really need to be fancy wity remote updates: at least require the push of a physical button to allow flashing remotely.
