Turn 2 VRC character prafabs into one prefab that can toggle between the two models?

Hi, I’m really new to anything Unity related, but I got a few VRC models and each one came with two versions (Pretty much just a difference in body) and I’ve been wondering if instead of it being two seperate models that I’d need to switch between in game, could I combine them and set a toggle to switch between them?
I dont know how easy it is to mess with prefabs or if ya can even merge two together for that matter.
But it’d be pretty cool if ya could, and if someone could tell me how.
I hope what I said makes sense.
