@Vineet S - Thanks for the question and using MS Q&A platform.
As per the ask we are not sure which source control with Azure Repos and GitHub.
To add two approvers to a pull request in Azure Data Factory, you can use the reviewers parameter when creating or updating the pull request.
Azure Devops: According to the official documentation: Add reviewers to a pull request
You can add reviewers in the Reviewers section of a new or existing PR. You can also make existing optional reviewers required, or change required reviewers to optional or remove them, unless they're required by policy.
Branch policies can require a minimum number of reviewers, or automatically include certain optional or required reviewers in PRs. You can't remove reviewers that are required by branch policy. You can change branch policy optional reviewers to be required, or remove them.
To see the branch policy that automatically added a reviewer, in the Reviewers section of the PR Overview page, right-click More options next to the reviewer.
Github: According to the official documentation: Require multiple reviewers for pull requests
As your projects grow in size and complexity, it can be challenging to make sure all of the code changes are reviewed by enough people on your team. Now, with a multiple reviewer requirement, you can specify exactly how many people are required to review every pull request—so important projects are protected from unwanted changes.
