Safety switch for Matek F405 Wing with Arduplane

I have installed Arduplane on a Matek F405-Wing and wonder is it possible to add a safety switch ?

Thank you

that board’s default pin layout is not designed to support a safety switch.
technically speaking, adding safety switch support would require modifications to the board‘s hardware definition file, trading in a default pin to act as the safety switch connector (plus another one to support the button’s LED) instead, and compiling a respectively customized firmware.
