It is possible on Stealth which is an accountless option with options to use a teddit instance. Little reason to even have an account anymore on reddit, and for those who say subs. Stealth lets you have a feed too. And those that say saving comments or posts Stealth lets you do that too. All locally and exportable.

If you continue using reddit on the phone why let reddit keep harvesting account specific data while just lurking? Go use stealth instead over doing stuff like patching past third party apps and logging in and letting them track your activity then being drawn to add value to the platform through engagement by being tempted to upvotes, downvote, and post.
