Ability to disable the caps notification?

[DaneelaArt]

I have caps lock bound to keyboard layout change, and every time i press it the "caps lock off" notification shows up. Is there already an undocumented option to do that, and if there isn't, can it be implemented?

Not currently unless you skip starting the libinput backend.

Would require #42 to be resolved first to have it as a option
