Is it possible to add a physics material to a CSG collision?

On CSG nodes, there is an option to “Use collision”, so that it will behave like a StaticBody, but is it possible to add a physics material to it somehow (like changing friction and the like).

Context: I’m trying to build some roads for a racing game, and I’m using a CSGPolygon following a path node.
