All you need to do is use the following launch parameters:
SteamDeck=0 %command% -dx12
Using this will make the HDR setting show up in the graphics config menu which is much more convenient.
Tetris Effect works if you use the fix mentioned here.
Using these launch parameters enable the HDR setting in the graphics options menu:
SteamDeck=0 %command% -dx12
