How do I exclude contributors of a MR from approving themselves in approval rules?

I want two other people approving the MR before it is allowed to merge, but it seems that the approval rules favors a group of static approvers.

Is there anyway I can exclude the contributors of each MR from approving themselves?

Is this the one are you looking for?

It’s in settings -> Merge request approvals, at the end of the section

Oh this looks very much like it, thanks!
