setting up a DEFAULTGPIO pulldown in bootloaders is a bad idea as it overrides any hardware pullups that have been put in place as part of a "hold in bootloader" mechanism. See discussion in #27360 for ELRS note that this only impacts one board that I can see, the BlitzF745AIO, due to the MCU vs DEFAULTGPIO interaction
