Purge or Truncate Tasks, Alerts, Events

[MCSAP]

I have been pretty successful in figuring out how to purge alerts older than x number of days via the powershell modules.  However, I'm looking at 50k+ tasks that I'd like to purge as well, but I don't see a command to do so.

Is there a way to delete older tasks from OV to cleanup and reduce the size of backups?

We do not expect customers to manage this.  OneView automatically will purge alerts and tasks once a threashold is reached.  Removing them with the process you are does not greatly impact the size of an appliance backup, nor appliance support dump.
