In GitHub, you can set branch protection rules in two ways:
Using the new Rulesets feature
Using the classic Branch Protection Rules interface
To configure these settings, start by locating your app connection’s Git branch.
Navigate to your application connection’s Settings page.
Under the 'Version control' section, you’ll find the branch details.
Branch Ruleset Setup Instructions
Navigate to the Settings tab of your GitHub repository and select the Rulesets section from the left-hand menu and click on 'New branch ruleset.

Ensure that the shared Git credentials for your app connection have permission to push. For example, if these credentials have repository admin permissions, add a bypass for repository admins.
In the Target Branches section, click on the Include by Pattern option and enter your app connection’s branch name.
For the remainder of the page, complete the fields according to your organization’s policies, for example:
Ensure the following settings:Enable Squash and Merge
Do not enable Signed Commits.
Once finished, click the Create button at the bottom of the page.
