Yeah I think that what you're looking for isn't going to happen, because of Samsung's skin on the Power menu.
But I thought you were asking how to know if you have android 11 installed?
One UI V3.0 is Samsung's android 11.
You might be able to try using Nova Launcher/activities or try using a shortcut maker?
He's looking for something else, that I don't think he can find on Samsung phones because of the One UI skin. I think that it's only available on stock Google phones?
