Permanently and completely disable onscreen keyboard for Ubuntu 20.04

I just installed a fresh copy of the (currently) newest Ubuntu LTS. Because I did this on an Acer with Touchscreen capability, it decided I want an on-screen keyboard which I very much do NOT. It's constantly in the way and completely unnecessary. I've been searching for days for a solution, but it's already off in the settings, I can't find any way to force remove it from the filesystem or otherwise make it behave. How do I deal with this nuisance? As is, there's no way the computer will work for what I need.
