I have new Dell XPS 8940 that came with Windows 10 Home installed.  I have
created two partitions for FreeBSD, one on its NMVe 256GB SSD, and one on
its WD 1TB HD.

For now, I have 12.2-RELEASE-p4 GENERIC on a USB memstick, so I can do
some limited testing.

FreeBSD 12.2 does not recognize the SATA/RAID controller, which I assume
is resposible (in Win10) for accising both drives.

The relevant pcoconf line for the controlleris:

   none7@pci0:0:23:0: class=0x010400 card=0x09c51028 chip=0x06d68086 rev=0x00 
hdr=0x00
      vendor     = 'Intel Corporation'
      class      = mass storage
      subclass   = RAID

See if the BIOS offers a choice of configuring the controller as SATA instead 
of RAID. That worked for me on an Inspiron 1180. (It also made W10 unbootable - 
apparently each OS occupies its own universe.)

That worked, precisely as it did for you: gpart list shows partitions and drives much to my expectations, and Win10 no longer boots. I can boot windows by setting the BIOS config back to RAID. That's not much of a pain. Now to try installing 12.2-RELEASE on the SSD!

Thank you very much indeed!
