Is it possible to change the DE without formatting?

For example, have a look at this discussion:

Moving from Gnome to KDE

Does anyone have any advice on migrating an EndeavourOS installation from Gnome to KDE? Is it as simple as: Ctrl + Alt + F3 sudo su - pacman -Rcnsu gnome gnome-extra pacman -S plasma reboot Possibly also disabling GDM & enabling SDDM. I’m debating whether it’s too much effort, and whether waiting for my next clean install would be better.
