Add way to disable haptic feedback while typing

I'm using feedbackd on the Librem5. And I personally don't like the vibration while typing on Librem5 squeekboard. I got so annoyed that I monkey patched out all lines in default.json which have VibraRumble and button-pressed/button-released etc. Using the silent mode isn't always a solution for me...

I wonder how a proper solution could look like, don't have something particular yet...
