Yes, I have installed NixOS on my GPD Pocket 2, which works OK. Have not encountered issues. The optical mouse actually works quite well and my hands can operate it with thumbs, while walking around or lying in bed, as well as more typical typing while stationary.
I would advise against getting a GPD Pocket 3. It's basically the size of a normal netbook and defeats the "pocket" monicker imho.
Depending on your distro you may have to set up a configuration that rotates the screen and/or digitizer to the right orientation.
