The built-in keyboard on my Pi 500 is acting up and, while I found a way online to fix it that looks simple enough, it'll be a few days before I have a chance to do it. In the meantime I've got another keyboard plugged into a USB port as a substitute.

The trouble is that after a couple hours the built-in keyboard starts repeatedly spamming the letter N on its own and I have to reboot to make it stop. Is there any way to tell the Pi to ignore its own keyboard inputs and only listen to the other keyboard for now, then reverse that when I get the main keyboard straightened out again?
