How to change pull request's target via Azure DevOps API

Question

The documentation says that the TargetRefName can be updated when "PR retargeting feature is enabled" but I can't find this option anywhere and can't see any documentation about how to enable it either.

How do I enable PR retargeting so that I can update the PR's target?

Click on the more action button(...) and you will see "Change target branch"
