Stop Windows 10 bootloader from borking NVRAM (via OpenCore)???

I read of a setting to protect NVRAM when booting Windows via OpenCore?

Was this just for AMD machines?

I'm asking because my Windows 10 borks my NVRAM ever 2nd boot (into Windows - macOS can boot forever with no issue).

I read there was an OpenCore setting (or quirk) that lets you do just this - am I misinformed?

I am using H370 HD3 from Gigabyte + i7-8700 + RX 580 8GB. I have used SSDT-PMC since it became available -> https://www.reddit.com/r/hackintosh/comments/erd2th/nvram_for_all_300_series_users_rejoice/

I am using an older OpenCore, so it may not include the fix? (0.6.1)

Any thoughts? it is getting rather annoying... PS. I do have PCI0.LCB in my DSDT...
