I think your best bet to start solving these issues is to try out -- after all your optional args. -- is a pseudo-arg that tells ArgumentParser that everything after is a positional argument. Docs are here

As for prevent arguments from being parsed after a certain point, you can pass part of argv to parse_args. That combined with some introspection can be used to limit what is parsed.
