I'm using Sonnet 350W with Sapphire pulse RX580, but it has undervolted vBios. Is it possible to revert it to default vBios in MacOS? If so, how can i do that? Thanks in advance.

Mac mini 2018 / i7 8700b / 32GB ram / 256GB ssd

install Windows 10 on a bootcamp partition, even if you don't have a licence you can run it for a month to get this done.

I was able to Flash mine from F1 to F2 using atifllash: https://www.techpowerup.com/download/ati-atiflash/ in BootCamp, with the eGPU connected and working.
