Remove a single line entry from vmx file for multiple vm's

I need some help removing a single entry from all my vm's vmx files.

The line in question is...

ideX:Y.present=false

I had added that line to all of my vm's vmx file because of security hardening. I need to remove that line because Veeam can't recognize that entry and errors out when a backup is tried.

The original script run was something like this...(just putting up the relavent parts)

$vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec

$VMX10e = New-Object VMware.Vim.OptionValue

$VMX10e.Key = "ideX:Y.present"

$VMX10e.Value = "FALSE"

$vmConfigSpec.ExtraConfig += $VMX10e

At the end there is....

$cluster = Get-Cluster $targetcluster | Get-VM %{

$_.Extensiondata.ReconfigVM($vmConfigSpec)

}

Appreciate any help on this
