Also if OP is hell bent on testing DEs on hardware, I recommend installing fedora silverblue and rebasing betweens the spins to try out KDE, Gnome, budgie, sway(and a few more provided the universal blue developers). This way you can can safely try out the DEs without the mess of leftover packages and without losing your data.
Also @Doctor_Rex remember to install the nvidia specific images from ublue. They will come the nvidia drivers preinstalled.
