In the photo I have all the outward facing normals/faces set to purple and the backfaces set to green. Is there a way in rhino like is some other programs that enables you to turn off selecting a mesh or surface when you select its backfaces.
Hello -no, there is not.

in case it is not too late, you can use clipping planes. placing it in the center of your object will hide the rest behind the plane so that you can access the inside, though that currently only works on straight geometry which in your case should be ok.
