How do you remove an Supplier Change approver who is part of an approval group

Summary:

We would like to ensure that a person who is part of our Supplier Change approval group does not approve their own changes

Our organization is looking at using an approval group to approve all internal changes made to the Supplier.

The catch is, it would be the same people who make the changes who approve them.
