What's triggering Intel SATA AHCI driver updates?

These Dells are funny animals. This relates to this post and the couple that followed. Had a very similar WU issue. On a freshly installed Windows 10 Pro on an old Dell XPS 8910 desktop with an Intel(R) 100 Series chipset, Windows Update updated the generic Win10 in-box MS AHCI driver to the Intel(R) 100 Series/C230 Chipset SATA AHCI Controller version 16.8.3.1004. I tried to reinstall the generic Win10 in-box MS AHCI driver, and it would not install. The install stalled/got hung up. So I’m forced to use the Intel AHCI driver.

On Dell’s driver support page, they offer the Intel-Rapid-Storage-Technology-Driver_2WR4F_WIN64_16.8.3.1004_A06_03.EXE

I can’t update bios drivers on this one - they’re all cyan colored protected. But I did run the bios through UBU, and this is what UBU showed me:

Main Menu
[Current version in BIOS file]
1 - Disk Controller
EFI Intel RST RAID Driver - 14.7.0.2341
OROM Intel RST for SATA - 14.7.0.2341
EFI NVMe Driver present

Maybe Dell has locked it down with the OROM Intel RST for SATA? I don’t know, but it’s interesting that the Windows driver Dell offers is v16, and the bios drivers are v14.

Anyway, I’m stuck with the Intel AHCI driver (which is not the end of the world). And my NVMe driver is the MS Standard NVM Express Controller.
