Give your subordinates clear and specific written instructions, eg: "Don't use x technique here, it is unnecessary.". You are the lead, part of your job is to overrule people sometimes.
If they ignore you, or fight with you, that is a different problem.
What this could be is a teaching moment, or series of them, depending on how cooperative or not the team members are.
