You can configure the Actions Runner Controller to run Dependabot on self-hosted runners.| GitHub Docs
GitHub automatically runs the jobs that generate Dependabot pull requests on GitHub Actions if you have GitHub Actions enabled for the repository. When Dependabot is enabled, these jobs will run by bypassing Actions policy checks and disablement at the repository or organization level.| GitHub Docs
Sometimes Dependabot is unable to raise a pull request to update your dependencies. You can review the error and unblock Dependabot.| GitHub Docs
