The way Avowed's third person camera option was presented in previews and in the new Obsidian RPG's first time launch options had us all thinking it was a semi-permanent choice, one you'd have to go digging around in a settings menu to adjust. I'm happy to say that's just not the case though: Avowed lets you quickly toggle your camera like most other first person RPGs.
In a preview build played by PCG senior editors Wes Fenlon and Robin Valentine, the camera toggle was exclusively accessible via menu, requiring you to pause the game, go to accessibility settings, and hit the toggle any time you wanted to switch. It seemed intended as a measure for players who suffer from motion sickness in first person games, a last resort for enjoying Avowed at all, rather than the casual quick switch we're used to from Bethesda joints or, indeed, prior Obsidian games like Fallout: New Vegas or The Outer Worlds.
