Hello. I hope you can help me.
I have an ASUS ROG GX800VH laptop and it uses 3 NVMe drives.
My problem is that in the BIOS there is no AHCI SATA mode, only Intel RST RAID mode. Because of this I can't install Linux OS, I need to switch in SATA Configuration from RAID to AHCI mode.
I made a backup of the region bios
It is available at this link.

I noticed that even in the program AMIBCP there is no choice of AHCI
Is it possible to add an AHCI selection in that case?
There are no SATA devices in the laptop, only NVMe disks

There is an opinion on the Internet that it is possible to deactivate RAID mode by setting the SATA controllers to disable
The problem is that I do not see in the Advanced menu SATA controllers --- enable/disable (used the AMIBCP)

BUT, the program showed that there is a menu Chipset and there is an option to disable and enable the SATA controllers
Here's a screenshot

Do you think this branch (chipset) is working?
If unlock this setting can it enable and disable the SATA controllers?

There is no SATA device in the laptop, I can sacrifice this painlessly
Please someone talk to me :)

@Lost_N_BIOS
Please help unlock the hidden "Chipset" menu
