Line Manager approving payment process request on behalf of direct report

Summary:

We are facing an issue in our approval flow where the 4th approver (who is also the manager of the 5th approver) is able to approve a payment process request on behalf of their direct report (5th approver).

We would like to restrict this behavior and prevent the manager from approving the request twice. Is there a configuration or setting within the approval flow to acheive this?
