I could be wrong, but I don’t think there’s a way for him to implement the keyboard change you’re asking for without modifying the keyboard’s firmware.
If that is a feature that @Kemal_Ozturk is interested though, I may be willing to help support the firmware changes needed to get that to work. I have already built a custom firmware for my RGB keyboard that allows me to see what my laptop’s utilizations and temperatures are at: RGB Keyboard Custom Firmware - PC Utilization Stats - Framework Laptop 16 - Framework Community
Without some pull/interest in that though from the community, I have no plans on doing that work. I’m relatively happy with where my keyboard is at right now for my own needs.
With some help, his framework control application could make the keyboard modifications relatively painless for an end-user.
