How do I make pathfinding ignore certain parts?

I was making a system using pathfinding, but I immediately ran into an error. I had a look at the navigation mesh, and it seems that it does not take Collision Groups into account. There are these large parts I have made which any parts outside the Default group can collide into, which the pathfinding system does not ignore. If it helps, I have used ComputeRawPathAsync(). Any help would be appreciated.
