Ignore that person. They think you’re meaning about how to downgrade to the current public version, but you’re meaning how do you ensure you don’t get anymore iOS 17 betas, only public releases.
The RC is ‘Release Candidate’ and is what is going to most likely be released on Monday, it’s not really a beta. Sometimes a slightly newer build gets released on official release.
As long as you have the option set to ‘Off’ in the beta updates menu in ‘Software Update’ you are off the beta train.
