Answer, there is no User Option to turn off stopping a Detector Collection, however you can limit access to PDT plans that control the product. See
PDTPLN05=PDTED200 PDT Collection Services<-------
PDTPLN07=PDTGD200 PDT Collection Profile Update<-----
You can control users from stopping the collection by refusing them access to PDTPLN05=PDTED200 and PDTPLN07.
