Anyway to change from KDE to GNOME?

Title.

Anyway to safely install and change from one to another?
If so, what are the steps?

I currently use KDE, but since I do a lot of desktop gaming, I'd like to change it to GNOME without re-installing everything once more. Additionally, is it safe to do so and go back to KDE without any setbacks?

I'm on ROG ALLY Z1e, using the bazzite-steam-deck image.

Please advise.
