Question about VRR

I have an AMD Ryzen 7 9800X3D 4.7GHz processor and AMD Radeon RX 9070 XT setup hooked up to a Samsung S90D as a monitor. Running Fedora KDE Plasma.

I can enable 120hz and HDR from my settings but see no way to set VRR anywhere. It works with the Playstation so I know the tv is capable. I asked AI a couple times just to get a rough idea of things I could try and tried the command

kwriteconfig5 –file kwinrc –group Compositing –key “VRR” “true”

but didn’t recieve a response so idk if this worked or not. Is this going to require installing AMD proprietary drivers? I briefly read a little about that and it looks like the process is quite a bit above my current skill level.

I saw a dev post about disabling Multi Stream Transport on the monitor but I could not find this setting on my tv anywhere so I think this may be a monitor only setting.

Any help or guidance would be greatly appreciated thank you so much in advance!

Question about an error recieved in terminal

(I am a beginner)
So I recently installed a fresh version of Fedora KDE Plasma after switching from GNOME Fedora because my understanding is that gaming is a bit better supported with KDE. (I switched because Cyberpunk wouldnt let me enable HDR even though it was on in GNOME settings and am on the journey of using gamescope and all that with this KDE install)

So the first thing I noticed is Discover absolutely WILL NOT let me download RPM versions of anything Flathub only even though I do have all third party repositories enabled. On GNOME I could just toggle a switch right on the software page to select which version of an application I wanted to install but no such luck here which is a bit of a bummer.

Normally I would use flatpaks but Steams flatpak requires me changing the udev rules for input and I dont think Im ready for all that quite yet so wanted the RPM version which I installed using the official fedora documentation to do so (https://docs.fedoraproject.org/en-US/gaming/proton/) and I did all of that and it did install however I encountered the errors in the pictures above and my questions are:

Can I just ignore this with no issues to my system?

and

Is this somehow related to KDE not showing me third party repository options?
