Universal forwarder is listening to the wrong port for the splunkd process

We are rolling out the UF to our windows servers, no apps yet, just the UF. The deploymentclient.conf only has the deployment server: targetUri = xxx.xxx.xxx.xxx:8089. this is causing some issues with another instance of SPLUNK our business folks have running. How do I change the port that the deployment server listens on How do I push this change to all the UF if they are not in a server class or have applications? Thanks!
