Can DCO be configured to not run on merges between protected branches?

DCO seems to essentially prevent being able to merge from a 'main-like' branch such as `main` or `dev` to a feature branch to keep it up to date. It isn't practical to ask all the authors who've contributed to `dev` to resign commits so we can keep the feature branch up to date with `dev`. Is there a way to supress DCO when merging between protected branches?
