| Aside from the environment variable solution, you could search

| you invoke argparse.

Although, speaking for myself, I like options to have effect as encountered:

  some-cmd -a --no-foo

Would turn on "all" options then turn off "foo". Hard to do if you look for
"more important" options and then less important options.

I'm personally against out-of-order option handling; it confuses things for the user.
If you (as the user) need the config file to be known first, put it first.
