Purchasing - Promise Date - How to prevent PO to return to Required re-approval Statut

Once the PO is Approved, and we manually changed the Promised Date, we do not want the Approval Workflow to do that.

Is there a PO configuration that can be done to prevent the PO to return for Approval a second time?

Thanks for your help
