I have a BGA with ground plane under it. The problem I have is that the ball pitch is too small to create a single ground (power)plane under it with all the via pads unsuppressed. See picture attached. Instead of having one GND plane I have small islands. Is there any way to suppress pads on vias that don't have connections on that plane so that I have more room to create a single GND plane? 


Thank you.
