Is it possible to completely hide the broadcaster's viewpoint and only show a guest's stream using the IVS stage feature?

I'm currently reading through the official documentation on the "multiple hosts" feature of Amazon IVS and one thing I don't fully understand is: Can I completely hide the broadcaster's stream to only show the viewpoint of a guest? E.g. in the example of the guide, can Alice be completely invisible to the audience and only Bob's video be shown in fullscreen?
