bios flash rx 470 - Issue

[mageerauld]

Hello guys, i want to modified bios(RX 470) with Polaris bios editor ""only value fan + gpu clock"",but i read in many sites Windows not know modified singnature...after flash bios every time need to use (when instaled new driver)Pixel Clock Patcher,Without patch your card will have error 43
So is a way to not have this error with bios modified?or only this error is from UEFI i have OS instaled in legacy mod? https://kodi.software/ https://dltutuapp.com/tutuapp-download/
