Disable Discovery Service

I am facing this WARN message that slows down the instance. For some reason the cluster change event keeps updating and changing. 

Is there a way to disable this service or configuration for a single instance that is not in a cluster? Already tried removing the default localhost topology URL.

org.apache.sling.discovery.impl.common.heartbeat.HeartbeatHandler checkForLocalClusterViewChange/.run: time since local instance last wrote a heartbeat is 669667ms (heartbeatTimeoutMillis=300000, heartbeatIntervalMillis=30000 => maxMillisSinceHb=240000).
