That's not how flagged (optionals) arguments work.

The default value is used if the flag is not provided at all.  One of your arguments is a 'store_true'.  Its default value if False, which is changed to True if the '--device-get-capabilities' flag is provided.

"nargs='?'" provides a third option, assigning the 'const' value if the flag is used without an argument.

In any case your problem isn't with a required mutually exclusive group (defaults or not).  It has to do with understanding optionals and their defaults.
