Anyone with admin permissions to a repository can enable or disable the automatic deletion of branches. Branch protection rules and repository rules can also prevent branches being automatically deleted. For more information, see 보호된 분기 정보.
For a pull request opened from a fork, GitHub uses the Automatically delete head branches setting on the head repository (the fork), not the base repository where the pull request is merged. Automatic deletion requires both of the following:
- The setting is enabled on the fork.
- The user merging the pull request has write access to the fork.
If either requirement isn't met, the head branch isn't deleted automatically. A user with write access to the fork can manually delete the branch from the merged pull request. For more information, see 끌어오기 요청에서 분기 삭제 및 복원.

On the "General" settings page, you can find a section called "Pull Requests". Under "Pull Requests", select or deselect Automatically delete head branches.
