Only if you wait until you're 3 miles offshore or back onshore to dump
it. A bucket is considered a "device" and is illegal to dump
overboard.

It's perfectly legal to "hang over the side" and do your business, but
if you came up with a toilet seat of sorts to bolt to the deck and sit
on, that would not be legal because it's a "device".
