Virtual machine detects a loss of guest heartbeat during vRanger backups

I'm getting warning alerts from OME reporting "Virtual machine detects a loss of guest heartbeat"  from the vmHBLost source,  during snapshotting process taken when vRanger backups VM's.

This doesn't happen with every VM being backed up but is a significant number to become annoying.  Is there away in OME to increase the threshold for this alert to either a number of attempts to time out or a set amount of time before alerts?

Obviously I can just disable that alert from the category and sources association list, but would rather have it on for when systems do go dark.
