Disable VMWare Tools time sync

When building templates with vcenter, the VMWare Tools option “Synchronize at startup and resume” option is always checked. We want this disabled as our domain controllers provide time sync to our VMs. The parameter “tools_sync_time” seems to correspond to the “Synchronize time periodically” setting. I’ve tried to use configuration_parameters to call out the API property for it but didn’t have any luck. Has anyone been able to disable time sync?
