Michele,
Unfortunately, the VR Object and VR Scene Cameras don't give you the option to control the viewer's limits. You can control what is being viewed and the camera view cone but not the actual camera limiting angle.
There are some other VR stitching/viewing applications out there that might give you a little more control.
