Make Disable Guardian Work Again!
Software Update v34 introduced a lot of really great features for people who are unable to play in VR in a distraction-free environment but it also overrode the use for the Disable Guardian option in Developer Mode to work while operating the Quest 2 device under normal conditions, now it "may only be used for content development purposes".
I have an anti-fatigue mat I use for added comfort and I never need to step outside of the mat for any purposes while playing, all of these extra features are just making it hard for me to enjoy VR.

You can try to create a very large play area around you instead. One that goes past your walls and stuff. That way you would never have to see the guardian even pop up.
