Are there any common drill attachments that go in place of the chuck?

So that when the chuck is removed, the attachment can be screwed on in
place of the chuck.

Like, a quickchange socket for 1/4" hex bits, or a sanding disk?
Anything that you can adapt to a (commonly, 3/8"-24tpi) spindle,
feel free to add to your hand drill. A three-jaw chuck, though, is
very convenient for most folk.
