HR users can edit their details from Approval workflow

Summary:

We have a requirement, where Local and Global Transfer goes for approval to HR Business Partner.

when the same transaction is initiated for a HR Business Partner, approval request goes to the same HR Business Partner and he/She can edit the details using the Edit button from the Notification page. we donot want the user to update the details in this case.

Content (required):

The custom role doesnot allow the user to search their record from any HR pages. Only issue is they can do this from the online Notification Edit page.

Is there any resolution for this.
