Prevent Autocolisions of StaticMeshes of the same actor in C++

Hi,
I have been looking for a way of disabling autocollisions between different URStaticMeshComponent of the same actor.
I’ve seen some options like using one of the 18 collisions channels and set it up and assign that to all the meshes of the actor to ignore themselves. But If I spawn two actors of the same class they will use the same channel and ignore themselves. I would like to know if there is an option to simple disable collisions between static meshes of the same actor, thats it. In similar way as you deactivate autocollisions in Physical constraints between the objects linked.

Is it possible?
