Yes, yoou can disable rotation pretty easily.  If you consider the
example in vtk/tk/vtkTkRenderWindowInteractor.py just add the
following:

    pane.bind("<ButtonPress-1>", lambda e: e)

and put it anywhere after you create the pane object.  Basically this
disables button 1 events and thereby prevents rotation.  Ofcourse this
is true for the vtkTkRenderWindowInteractor.  I havent checked the
default vtkRenderWindowInteractor.  You might need to add an observer
for that class.
