detailed instructions here for using a firmware mod and a systemd service:

i'm not sure how this will interact with an external keyboard though - does changing the firmware change just the mapping of the device keys of the laptop, or does this also remap external keyboards? i think it's the former, but i have to be sure before potentially making some irreparable changes to my system
