There is the MOD Dwarf, a Linux based pedal that is much as you describe. It has a pedal style case with three foot buttons, a few encoders and buttons and screen for changing parameters on the fly, but to fully configure it you use a laptop or tablet to connect to it and set up a patch.

That's a lovely little bit of hardware, and it's not actually that expensive too! Great recommendation, thank you.

Seems better than the absolutely crazy custom one I made myself when I was like 22

Also just normal computer footpedals that were like 34.99 worked great for controlling the software if there's extra things u still need to assign

That's really cool!
