I don't know yet if this is reproducible, but I deleted my app, reinstalled it via TestFlight using visionOS 2.0 beta 4, presented a full immersive space in the app, and then I saw the Stay Aware of Your Surroundings alert.
So, that is a possible means of reproducing the new visionOS 2 full immersive space behavior.
