UEFI BUG? Intel RAID Option Not Staying on Lenovo IdeaPad 320-17IKB

Hello,

My BIOS has 2 options for the SATA mode: AHCI and RAID. I switch it to RAID, save and exit. But it keeps returning to AHCI. Can someone help me to set this to RAID? Thanks in advance. I will pro ide my already a bit modded BIOS dump. It is an InsydeH2O BIOS. I also alpreciate if someone can find out the key needed to enter the RAID setup. Thanks in advance!
