Thank you, perfect idea to post that there.
I used in the past this script to enable that feature on all my VM's:
Connect-VIServer -Server vcenter.server.local -user administrator@vsphere.local -password PASSWORD
$vms = get-vm -Location "Datacenter-Name"
foreach ($vm in $vms) {
New-AdvancedSetting -Entity $vm -Name snapshot.alwaysAllowNative -Value TRUE -Confirm:$false -Force:$true
}
