Pretty sure you can't unfortunately. Achievements're here to stay as of the seventh generation of consoles. Apologies for the bad news mate. I wish there was a way to reset achievements other than reinstall the game entirely or [if you're on GOG Galaxy or Steam, not sure about the former, but definitely know this's the on Steam] create a new account altogether. Sorry mate. Hope that answers your question.
Edit: Nevermind. Comment above mine answered that question apparently. Disregard my comment. Sorry about that.
