Is there a way to disable / suppress pipenv's "Courtesy Notice" about virtual environments?

Each time I invoke pipenv I see:

Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead.

Can this be globally suppressed?

My current workaround:

pipenv lock --requirements 2> >(grep -v "Courtesy Notice" >&2) > requirements.txt

Does PIPENV_IGNORE_VIRTUALENVS=0 have any significance? If pipenv was told to not ignore virtual envs, then that should mean I want to use my existing virtual env, and the courtesy notice should be suppressed.
