Is it possible to turn ON raytrace through the cmd line?

Some of the raytrace settings exists within the Properties panel of the project. I am building my own lighting menus with blueprint utilities. I have not been able to find a way to change the Properties through blueprints, or the CMD line. Is there a way to get a bool back telling me that Raytrace is on? Can I turn it on with a widget button from within Unreal? If not, what about using Python to do it?
