Preventing reordering on a resource route

Summary

This question is related to OFS.

Currently we are trying a new method to re-optimize during the day multiple times, we have the optimization strategy set at "Move activities between resources routes and reorder within the same routes" selected and we created a filter for the "Preassigned activities filter" with some conditions needed for this trial. We are looking for an optimal way from preventing certain resource types from getting jobs re-ordered or re-optimized

Content (required):

One of the conditions added to the preassigned activities filter (see screenshot) is to restrict certain user types, however we have seen multiple instances where these resource types are getting their routes reordered but not re-optimized. Would this filter only prevent re-optimization but not re-ordering? Is there a way to prevent one user type from getting re-optimized AND reordered with the settings that we currently have?
