How can remove the Camera lens bracket and ring from back glass?

You see that ring of dots around the camera bezels? Those are marks from a spot welder - mini micro edition. The bezels are spot welded on, meaning there's no simple or easy way to remove them. They can be torn off with brute force, or ground off with a Dremel-type tool, but no matter how you get it off, then you're left with the question of how to put a replacement back on? Nobody I know has a spot welder like the one Apple uses, but maybe you could get away with one like they use for battery terminals; obviously it won't be as neat as the original welding job, but it could theoretically work. I suppose you could superglue it in, but of course you'd want to remove the back glass panel from the phone before doing anything; wouldn't want to take a chance on getting glue in the camera itself.

Basically there is no really good option for you here, Jairus. Besides the difficulty of the job itself, I'm not aware of any vendor actually selling those bezels.

Ordinarily I'd suggest just replacing the back panel, but of course Apple strikes again with their parts pairing; the rear panel is almost certainly paired to the motherboard and will complain bitterly and permanently if you replace it with an aftermarket part. If you're up to date with iOS 18 there's the Repair Assistant that will let you pair a genuine Apple rear panel to your phone. As long as the phone it came from isn't reported lost or stolen, you can pair a used part, so it doesn't have to be new, purchased directly from Apple, but it does have to be a genuine Apple part no matter what.
