The best answer itt is the one that tells you to reduce the number of coin flip situations you go for. But it has to be a true either-way decision to really have no effect on variance/standard deviation.
Poker is a game of variance. Most of your decisions will be based on uncertainty, so will include variance by definition. DD was saying that playing only the nuts is low variance, and I added that not playing is lowest variance - both these are reducing the game to certain decisions, removing uncertainty, and removing variance.
Your primary aim in poker is to increase your edge. If you try instead to reduce your variance, you will be missing out on a lot of profit, so this will affect your winrate.
