It may or may not be easy, depending on your environment, but you can remap keys. I have `input * xkb_options "caps:backspace,compose:ralt"` in my ~/.config/sway/config, for example, plus `input ‹laptop keyboard identifier› xkb_file "~/.config/sway/keymap.xkb"` with that file fixing XF86AudioMicMute (which has key code 256, but X only supports up to 255 and I’m still not quite sure why this was necessary), and now remapping RShift to LCtrl which died early this year.

But… ouch. From https://itsfoss.com/remap-copilot-key-linux/ and other sources, sounds like the Copilot button is LMeta+LShift+F23. Why a combo when using an esoteric key not on anyone’s keyboard anyway? Ugh. That’ll make it harder to sort out, though still possible.
