Using (just) 8GB of RAM in a NUC 15

I want to build an ASUS NUC 15 Pro i3 mini PC with 8GB of RAM.

Now I’m faced with the following dilemma:

NOTE: 2 Gb, 4 Gb, and 8 Gb memory technology (SDRAM Density) is not
supported.

Does ASUS provide conflicting information on their homepage, or does the note mean something different than what I think it does?
