[Request] Need enable Legacy Boot on PH315-51-78NP InsydeH2O

I need enable legacy boot because i cant access intel rapid storage in UEFI bios and my bios doesn’t have legacy boot option
My original bios file: drive google com/file/d/19KMxibpTcDkwq83RPbqlTIiXmhY2–X-/view?usp=sharing

Hi! I can unlock your BIOS, but we need to perform preparation, just like for your XIaomi to avoid error on flashing. Download H20UVE_100.00.9.2.zip, extract to a separate folder. Run "GET VARS.bat". I need "vars.txt" file.

here’s my vars file, can u mod unlock advance setting too?

vars.txt (197 KB)

Ok. Here’s your BIOS mod. "SET VARS.bat", REBOOT, two clicks on FLASH.bat.

i got this error after set vars, reboot and flash
Error 167: Protected Range Registers are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable
Protected Range Registers.

Fixed. Please, re-download.

I can see legacy boot now but when i switch to it then save setting my laptop cant boot to bios, after a while reboot bios set boot option to uefi again

I cannot influence this, I just unlocked this option. It was already there, but I just allowed it to be shown. Maybe the manufacturer did this because it is not supported.
There was also a Dual Boot Type in your BIOS. Perhaps your system will be able to boot with it. Wanna try?
