You can move the frame out of the way but arbitrarily clicking something behind it won't work.
If you replace SetPortraitZoom with SetPosition you can move/zoom the model inside the frame. You can select/view the methods available for the various UI widgets
here.
Depending on what you are actually trying to achieve there probably needs to be far more work beyond this rough outline than I have time for.
