Reverting back to iOS 17.5 without any PC and no type of back up

Hello Apple, if you don’t know me, I can’t give you my name but I recently have updated to iOS 17.6 beta 2. And I would like to revert back to iOS 17.5 with no Mac and no back up because I forgot to do a back up and I don’t know if it might become an issue with iOS 17.6 beta because this is my first time ever doing a beta and I am very concerned Because one hour ago I updated and I had a lot of bugs on my phone. Can you guys please revert me back to iOS 17.5 with no backups and no type of Mac.
