The Exclude Technician from Geolocation Tracking permission allows disabling geolocation tracking for specific service resources by assigning them a permission set with this permission. Setting the Geolocation Update Frequency field tozero for contractors would not disable geolocation tracking, but would make it update less frequently. Unchecking the Geocoding field on the Contractor's profile or the Collect Service Resource Geolocation History field in Field Service Mobile Settings would not affect geolocation tracking, as these are not related settings.
