title: Azure KeyVault Enable or disable secret key from c#
body: <p>I have been looking at an option to enable the secret key in the key vault from C# with managed identity.
  I have full permissions and I am able to create, delete and change the secrets but somehow, if I create a disabled secret key, I cannot read that to re-enable it.
  Could anyone help to know whether it is possible to enable the disabled key from c#?</p>
