Respond to Ping

Good afternoon,

Is there a way to programatically check/uncheck the 'Respond to Ping' option found in the vPro WebGUI?  I would like to do this using Powershell, but any method would be helpful.  I can't locate this setting anywhere but within the WebGUI.  In fact, even when I run the SCSDiscovery tool this setting isn't represented in the registry.

Thanks.
