there is something that I've said on here many times. I even wrote a big thread that got much scrutiny. The more post flop play, where you have an edge, the less variance. The more post flop play, the more chances you have to win with the worst hand. This is only of course if you have the edge in post flop play. Because the same holds true the other way. The more post flop play, where you have less of an advantage, the more variance.
Variance is decided by the winning or losing with the worst hand, and winning or losing with the best hand. If you are running well, your good hands are holding up and your bad hands are sucking out. And the opposite, when you are running bad, your good hands can't win, and your bad hands can't suck out...but imagine you got the chance to play all those bad hands post flop with an edge. You now have that edge on every street. You now have more chances to avoid variance by outplaying your opponent. So in conclusion, if you have an edge post flop, then playing with more postflop play should reduce variance.
