In some situations, I do not want to provide users with overrides or at least, do not want to provide users with explicit help that they can override by providing Ansible variables. These could be two use cases:

1. Prevent the use of -e
2. Prevent the display of -e from the help text

Right now at the bottom of the help users see:

advanced arguments:
  -e EXTRA_VARS, --extra-vars EXTRA_VARS
                        set additional variables as key=value or YAML/JSON, if filename prepend with @
