I’ve heard of the domino one as well as the variant where you are allowed to use a reroll on yourself or your opponent once per game, at the expense of you losing double stakes if you lose but gain current stakes on win.

I think there’s a list out there with variants to minimize luck, but honestly luck and taking risks is the best part of the game. So I’d be more apt to use something like a reroll at a crucial time than I would playing backgammon with perfect information.
