If you have a pro it’s easy enough to cut the end off or just use it “vertically”.
Otherwise you can “score and snap” acrylic pretty easily or use a jigsaw/hand saw with an appropriate blade…
It all comes down to how much time you’re willing to spend messing with it.
If you don’t have a pro you can trick the gf into running with the front door open. Not that I’d advocate breaking safety protocols, but people have done it. It involves magnets and whatnot though I haven’t looked too closely because I have a pro. You’d be able to cut the end off easily if you pulled that trick.
