I have three CDN Front doors I am trying to delete. I no longer own the domains and it keeps failing. How can I delete these domains? I have tried the following command, but it doesn't seem to be working.

az feature register --namespace Microsoft.Network --name BypassCnameCheckForCustomDomainDeletion
