I'm biased to immutable distros ever since I tried Fedora Silverblue. It's stable with rolling release. I have used the rollback feature once when gnome kinda got messed up in an update. I think gnome is touch friendly but never tried it myself in a touch device. There's also vanilla os, another immutable distro which based on Ubuntu atm. They're supposedly rebasing to Debian in the future.

From what I've heard Debian is rock solid on the servers. Not so much for a desktop use. Since you're on a unusual device i might have suggested manjaro, endeavour and the other arch based oses. But that's close to playing with fire. It's easy to break but you'll get the latest software on the edge. Manjaro even seemed to check for the proper drivers when I used it long ago. Pop os is great for nvidia users.

There was a GitHub link somewhere above. Check your device. See what works with the mainline kernel and what doesn't. You could hopefully look for patches for stuff that someone have put out there. If not you're out of luck for that feature with your device. Ideally, you'd be the one working on it. But if you don't have the expertise, you could raise issues and hope someone finds it important enough to work on. Using a rolling distro, you'd get the feature as soon as it is mainlined to the kernel.
