Protection control

The owner of the repository can bypass the branch protection control.

Hi @Edward-Wang-Foris, welcome to the community
By default, protected branch rules do not apply to people with admin permissions to a repository. You can enable this setting to include administrators in your protected branch rules.
See step 10 of managing-a-branch-protection-rule

Although a repository admin can themselves amend the branch protection rules that apply to a repository, but that would need to be a deliberate action, and changes to branch protection rules are audited actions in an organizations audit event log.
