renovate/lib/modules/datasource/galaxy-collection/readme.md

By default, the galaxy-collection datasource checks for dependencies on https://galaxy.ansible.com. But you can override the default if you want.

Set your own registries by:

• setting a source in your requirements.yaml file, or
• writing a packageRule to set a new registryURLs

Then you can use Renovate with a private automation hub.
