How to exclude a commit from being included in the changelog?

Hello! I'd like to exclude certain commits from being included in the changelog. The only information I could find was how to include multiple changes in a single commit.

One use case of this are commits that adds features to internal APIs that are not exposed. I'm not sure if there's a better commit scope than `feat:` for these types of changes, but from my interpretation of the conventional commits guidelines there's no better candidate.
