Is there a way to force UF to phone home to DS?

Hi All, I just want to ask if there's a way to force UF to phone home to DS, we want to initiate a force phone home without editing the phone home interval under the deploymentclient.conf, currently the UF is set to phone home to the DS every 6 hours but we have a requirement that sometimes it is required to force phone home to the DS asap. I've already tried restarting the UF and running ./splunk reload deploy-server on the DS to see if it can trigger the UF to force phone home to the DS but it does not work, is there a way to do this, any suggestion can help. Thanks and regards, ...
