Yes. As long as you have a backup of your vbios I would proceed. (or does your card has dual vbios?).

You can always boot back to Windows and flash the stock/backup vbios back.

Yes, as mentioned by @Yomiro , this is safe to do as long as you have a backup and nothing goes wrong flashing the vbios.

However why would you want to update the vbios if you can simply inject the desired card behaviour using a PowerPlay table (PP_PhmSoftPowerPlayTable) in your OpenCore config.plist?

Thanks for the info @mattystonnie !!
Hi there...a bit confused I'd like to test this with my RAdeon Vii too. On Catalina (Clover) I already have 94589 Geek bench metal and 75384 open cl scores... so a wich ssdt should I use and does this wor in conjunction with the radeonboost kext? I also have a new BIG SUR Open Core drive on which I'd like to try. (Will eventually move the caltalina drive to the OC drive.

RadeonBoost stopped working quite a long time ago. Don't remember exactly which version but I haven't had it installed in quite a long time. If you want to try just install the kext and it should work.

RadeonBoost and the Enhanced performance SSDT from @mattystonnie both stopped working at the Big Sur transition. Although with the 12.2 > 12.3 upgrade, it looks like the SSDT is rescuing some of the higher end Navi's from some sort of driver glitch. We're hoping that @mattystonnie might come back around to help figure it out....
