If it were, I think things would slow to a crawl. 3D projected floor plan display is already quite slow sometimes, constantly checking for that toggle would probably be horrible in terms of speed.
Anyway, check the globals, they're listed at the very end of the GDL Reference Guide (found in archicad help menu, but I'm sure  you are familiar with that), if something exists, it would be there. You generally can't run those statements in parameter or master script though.
