No it isn't. Or, better said, it wasn't. Storing of NVRAM is a new feature in 4.4.5 and it will be enabled only for VMs with Secure Boot. So whatever you're experiencing is probably caused by something else.

> Is there a way to clear NVRAM for a VM without deleting it? This is not part of the feature introduced in 4.4.5. But it would make sense to have it if we later extend the NVRAM storing to all VMs with UEFI. So despite what I wrote above it would be worth opening a feature request bug.
