Tech Support indicated today based on SN and end November timing of purchase the board "likely" has version 1.19 - released in September which supports Cascade Lake. GPU due Monday, so will report back next week if posts or not. 

So I got ahold of a i5-7640X and it booted into bios no problem. My MB was on v1.07, And after updating to v1.20 my 10980XE works great.

Great news I plan on getting a X299 Dark and a 10980xe with some team group xtreem ram

I bought it, I found the i5-7640X for $150. So I will keep it around as a backup. Maybe one day i'll overclock it, And see how far it can go 
So far I have my 10980XE at 4.7GHz 1.184v, 32x Mesh 1.125v for a daily clock, And I've had it running in some benchmarks @5.0GHz 1.27v. But it's not 100% stable mostly because it get's hot fast over 1.2v.

To close my portion of this thread, received the GPU and on Dark system first boot received the DF post code from board recently purchased.
Had previously requested 1.20 chip from EVGA Support and received in mail. Installed new chip and next boot was ok.
Thank you for the support.

I ended up having to RMA my brand new x299 dark because the little BIOS socket popped right off when EVGA sent me the replacement chip with 1.19 on it.  This has been a bit of a nightmare build for me so far.  That said, the RMA board came with 1.19 on it and I booted right into BIOS and I updated to 1.20 already.  Hard to believe the tear down, rebuild, tear down again, RMA, and now this weekend rebuild again all for a BIOS update when these were supposedly "ready for next gen".  That said, as always EVGA made it right as quickly as possible.  EVGA is the only reason I am not on an AMD machine right now.
 
couple of notes:
 - The EVGA information sheet I received with the replacement BIOS chip mentioned an index triangle and a white dot on the BIOS chip to assist with orientation.  Neither are there in my case.  There is a tiny indented circle on the chip and it is the best way to make sure you have the BIOS inserted correctly.

- The BIOS socket is more fragile than I expected.  The BIOS hatch doors have a left side / right side that are tabbed and the one flap has to be opened first.  I think they should be numbered right on the hatch, but at least make sure you are careful and just use your fingernail when you try to open it.

I have the same issue, brand new board, tried to open doors gently with a toothpick but they would not open and applied just a tad bit more force and bios socket came loose, contacted evga tech support and he insisted that they tried themselves to break them loose and its bot easy but mine popped off easy without much force and i was denied RMA because its physical damage, i have no idea what to do with board now.
