When will one ui 2.0 will be available for Note 10 plus in USA?
When it is
Beta is available now, actually I have been running it for at least two weeks.
If its available how do we sign up and install it?
It depends on what region you are in. But you usually get a notification from this app to download it.
How you get beta?
Good question. I purchased my Note 10+ directly from Samsung (unlocked) and enrolled in the Beta as soon as it was available. Never heard or saw a thing.
