Ask them whether their board hardware supports a headphone jack via Intel HD Audio - the non-N suffix model NUC10i7FNH.
It’s very likely, however, they are using the N model suffix version NUC10i7FNHN, because I guess the non-N was discontinued a long time ago.
I believe they stopped doing that because Roon’s license for Rock does not actually allow it
FYI:
The dimensions are 15,7 x 15,7 x 12,2 cm and the Cirrus7 Nimbini v3 has to stand upright for better heat dissipation.
Your absolutely right - great customer service.
This is the BIOS information on my NUC & the Intel Audio Devices in Roon. I can’t confirm that any of the HDA Intel PCH HDMI devices work only that they are listed as Audio Devices. You should definitely confirm this with the supplier! There isn’t a HDMI Surround as shown in your image.
No problem.
In fact, HDMI doesn’t work for multichannel.
After a little research, it turned out that this applies to all 10th generation NUCs. It will only work on an outdated NUC8.
I don’t think that this is the case. As @wklie wrote earlier, if there is support for a headphone jack via Intel HD Audio, then multichannel HDMI is supported. This is certainly true for the NUC10ixFNH models.

Okay, I just relocated my NUC10i7FNH in order that I could run a test via HDMI. I don’t use any Multichannel sources for music, only AV. I downloaded a simple 1,2,3,4,5 voice test and can confirm it outputs via all the surround speakers. I would also agree with @Geoff_Coupe that the issue seems to be with NUC10s that don’t have a headphone jack.
Hope this helps and best of luck when your unit arrives.
@Scotav - I will have to wait an see 
I have just ordered a cirrus7 nimbini v3:
