Tree Leaves - Snow on one side possible?

I am struggling to figure out if its possible to add sloped snow/up vector snow to tree foliage that appears on only one side. I want the snow on the top of the tree leaves and on the backside to of course be the normal green snowless leaves.

I have the slope working fine on top, no different than what I use on rocks for snow, however, the issue I am running into is that the snow appears on both sides of the canopy cards. The underside appears snowy as well. With a Subsurface color similar to my diffuse the snow effect isnt TOO strong but its still kinda white and not what I want.

Is there a way to have a 2 sided card render basically 2 different looks? One side showing off the snow on top and the other side without snow? Not sure if thats possible.

Thanks!
