Zoom Info & Sugar Integration - Catching Duplicates

Hello! We have Zoom Info (ZI) and Sugar integration via Sugar Connect.  When a Sales rep imports a contact, it doesn't catch duplicates.  ZI is telling us to turn on list and export capaibilities. We DO NOT want to do this b/c we don't want our people exporting sensitive information.  

Is there another way to catch duplicates when importing contacts from ZI?
