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.

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.
