Well... Michelangelo hand polished glass into telescope lenses in the 1500's... So I'm sure its **theoretically** possible - But I sure wouldn't want to be the person doing it: I think my arm would fall off. And again - be sure to develop a technique and combination of polishing fluid and clothes on a test part first.
Keep in mind you can get polishing kits for your drill for dirt cheap on Amazon, Temu, AliExpress, etc.
