No, those are not mounting holes. This board doesn't require heat sinking, it comes with some double-stick foam tape.
I don't have a mounting box for it yet, but I'll probably work up a 3D print bracket for it so it can slide into the rails that the heat sinks slide into, or maybe onto the heat sink rails.
