How to Skip Workflow Rule when requested for and Approver are same in HCM

Summary: How to Skip Workflow Rule when requested for and Approver are same :

Used case : When HR admin or HR manager does an Assignment change or Salary change , Approval hierarchy is defined as ( Level 1 Senior HR Manager and
Level 2 Head of the Department . both the roles are AOR ( area of responsibility) based and workflow is defined based on AOR .

Scenario :
If HR manager is changing the salary for a person ( Mohammed ) who is also a Head of the Department of his department , in this case , workflow is going to him only for the approval , which ideally should not go , so how can we skip the workflow when we raise a request for a person who is one of the approver in the workflow hierarchy.
