Any way to NOT import materials

[imfastrnu2]

Is there any way to NOT import materials with my Solid Edge models? And if not, is there any way to delete the ones it imports? When I try to delete them from the scene tree, it deletes the parts. And if I'm in the Materials tab, there seems to be no way to get rid of them. i want to apply materials directly in KeyShot and ignore the crappy materials from Edge. Thanks in advance.
