HDR in bazzite-deck-nvidia works great! Now is there a way to get it working in desktop mode?

I wanted to see how well Game Mode works in the latest bazzite-deck-nvidia release and I am really happy to say that it's practically flawless! There are definitely issues with the interface, but it's great to see HDR working so well on a linux nvidia setup. It got me to thinking though, is it possible to get HDR working through Desktop Mode?

I tried before using the gamescope launch option, but there were always issues. Now that bazzite-deck-nvidia is out, is there maybe a better way to do it?

My goto was always gamescope -H 1440 -W 3440 -e -f -b --hdr-enabled --hdr-debug-force-output -- %command% but this either caused steam integration to fail (despite the -e flag) or the game to crash.
