VR/NonVR in same program?

Hello, I am relatively new to making programs on unity. I am basically wondering can i set up a program as a normal app on android. And then hit a button to open up a different scene in VR for cardboard? I am not sure if this is something that can be done or not yet. The only thing I am thinking is does a whole project have to be completely set to VR for it to work, or can i set it to a setting?

Any help at all on this topic would be greatly appreciated.
