On Bazzite 42 Gnome the VRR experimental feature is disabled by default
After updating from Bazzite 41 to the new 42 version (main, not testing), I noticed my display does not have VRR anymore, not even the option to enable it.
Following that, I rebooted into the previous image, which is Bazzite 41, and the VRR is available and activated for my display as expected.
On Archwiki I read about the experimental setting, so I suspected the experimental feature to be turned off in the new 42 update.
After running the following command, and re-login to activate it, VRR was present again as an option. More so, it was automatically enabled again for my display as it was on Bazzite 41.
