Need to know if we can turn off dnd while gaming

Will I be able to update to a stable one ui 6 version when its released while I am on a beta version? Without any extra steps and data loss?

I have withdrawn from tha beta program however I am not getting a downgrade option in smart switch app

I am using S22 ultra, recently I noticed that the display is always locked at 120hz and it doesn't change for anything. I tried viewing picture, videos, different apps, idle home screen. It is constantly at 120hz. Is there any troubleshooting methods...
