Does this moterboard really support 2x Ultra M.2 ?

The link above is the official link to my mobo and its description. I checked and the description says:
"6 SATA3, 2 Ultra M.2 (PCIe Gen3 x4 & SATA3)"

When I look at the motherboard, I'm not sure I see a second slot for another ultra m.2 drive. Am I misunderstanding the description?
Forgive me if I'm missing the obvious here, English isn't my first language. Thanks guys

P.S. Also if you don't mind my asking: What is the difference between an m.2 that is PCIE based and another that is SATA based? I've done some research, and I keep finding explanations where they compare an m.2 to a traditional 2.5" SSD drive, but not the two m.2s
To make my question clearer: M.2s can apparently have the same "form factor" but be "SATA based" or "PCIE based" and this is where I'm confused

Yes, main one is in a usual spot, in between the CPU socket and above the first PCI-E 16x slot, and then the 2nd is bottom right corner, above various headers.

Omg thank you so much! lol
It was well hidden behing my graphics card (my graphics card uses a special adapter that makes it STAND up) so it hides a good portion of the mobo

I guess my next question is:

• If I plug in a M.2 drive into ONE of my ULTRA ports, will my Graphics Card drop from x16 pcies lanes used to x8?
  • What about if I use BOTH of the ULTRA ports for TWO different M.2 Drives? will it then be x8 for the gpu and x4 for each of the m.2 drives?

Look through the manual, it should explain all of that. I doubt that it will take away from PCI-E lanes, but usually when using one or the other, or both M2 connections will disable SATA port(s).

yes when reading the manual, it does seem to indicate that both ultra ports support pcie 3.0 x4 lanes
so I guess both would work without affecting the GPU.
I'll boot in the bios to see which SATA ports I have used atm to make sure they're not included in the list of SATA ports that are disabled when using both ULTRA m.2 ports.
The manual says SATA3_0 is disabled once I use a PCIE based m.2 drive in M.2_2 port
