Is it possible to render the first person completely seperately. Not panini related

Ive tried multiple different scopes, on multiple different weapons, as well as modifying the geometry of the scopes to try to avoid this problem, and you’re underthinking it massively. You almost always see the geometry of the scope interior/front sights/barrel unless the zoom on the scope is massive. Anywhere from 2x-6x ive tested and you could always see something. It dosent look nice, if you want to make something look AAA you cant just ignore this issue.
