Adding nodes & monitoring disk/memory via PS using WMI

Would someone be able to help me out with getting the monitoring to automatically select all hard drives?

I have used the script CRUD.AddWMINode.ps1 to add the node into Solarwinds and been able to add a custom property but it is only monitoring the CPU & Memory.

How can I enable the monitoring for the following items?

I have the following script to add the pollers but this only works if the disks have been ticked in the above window?

#get volume id of the volumes added to the node

$Node = Get-SwisData $swis "Select nodeid From Orion.Nodes Where Caption = '$SystemName'"

$VolumeId = Get-SwisData $swis "SELECT volumeID FROM Orion.volumes where NodeID = '$Node'"

#add pollers to the volumes

foreach ($volume in $VolumeId) {

    $poller = @{

        NetObject="V:"+$volume;

        NetObjectType="V";

        NetObjectID=$volume;

    }

    $poller["PollerType"]="V.Statistics.WMI.Windows";

    $pollerUri = New-SwisObject $swis -EntityType "Orion.Pollers" -Properties $poller

}
