Problem switching my default monitor for Steam Game Mode
So I just installed Bazzite on my old laptop and was hoping to use it as a sort of steam machine for my living room, but I can't figure out how to get Steam Game Mode to show up on my secondary monitor (TV). It only ever shows up on my laptop screen, although when in Desktop mode, the TV screen works just fine. I've tried the whole Quirks and workarounds trick shown here: https://docs.bazzite.gg/Handheld_and_HTPC_edition/quirks/, but it doesn't seem to work. The correct output should be HDMI-A-1, as I only have 1 HDMI port on my laptop, but nothing happens when I save the file and reboot. Is this a problem because I used the Nvidia Version and not the AMD one? Should I try Gnome instead of KDE? (I happen to quite like KDE and would rather not swap to Gnome)
I'm extremely new to Linux as a whole, so any help would be greatly appreciated.

Some Info if it helps:
My laptop is an HP Victus
i5-13420H

Using KDE
