How can I unregister huggingface as a model provider?

[andersfylling]

I want my pi --list-models to only show models I've configured, same when I do /models in a pi session window.

For anyone stumbling here, huggingface shows up as a provider because you probably have the env var HF_TOKEN in your shell config file.
The same happens for all environmente variables listed here: https://pi.dev/docs/latest/providers#use-an-api-key-from-the-environment
