So it seems I did not do enough research and purchased the core X + asus gtx 1080 turbo, only to find out after several hours that Nvidia dgpu and egpu dont play nicely together in a hybrid graphics system.  Is there any hope?

I've tried uninstalling nvidia drivers through windows, but the quadro always comes back.  Thunderbolt 3 port recognizes the core X, just never the gtx1080 card.  I finally disabled the pcie port for the quadro and its finally gone, core X recognized, but STILL no gtx1080 card shows up...

Appreciate any info.  Thanks.

I have an nVidia dGPU (M1200) and eGPU (1080Ti), no such nonsense occurs here (there is a stutter issue, but that one has a solution).

Since your issue is that the GTX1080 doesn't appear in the device mananger: Your issue isn't the dGPU, but something else entirely.

1) Are you sure the GTX1080 is in working shape? Can you test it in another system?
2) Are you sure the Core X is functional? Can you test another card in it (doesn't have to be a graphics card)?
3) Do you have any new "VGA" device in the Device Manager? Does the GTX1080 appear but with an error?

Give your Node Pro a second Thunderbolt3 controller for reliable peripherals by re-using a TB3 dock (~50$).

Make sure your P51 allows Thunderbolt to actually use the PCIe connection and not just Displayport and USB. I'm not sure if the Core X would pop up then but it's a check in the BIOS/UEFI that doesn't take long.

Might be difficult, as I only have laptops, and this one may be the only one with a thunderbolt port....
The core x is recognized by the thunderbolt program and shows as connected; just cant see the gtx1080....doesnt even appear anywhere in the device manager....
thanks for your input.

How would I confirm this?...that thunderbolt port uses PCIe connection....everything thunderbolt related is enabled in the computer BIOS.  Thanks for the help.

Go into Device Manager, change the view to "By connection". When the eGPU is connected, Some additional Thunderbolt buses should appear connected to one of the root Thunderbolt buses. Maybe one of them has a Thunderbolt USB controller. And one of them should have the GTX1080.

update:
It turns out its the asus gtx card.  I took the core x and asus gtx to work where we have a laptop with thunderbolt and some desktops.

asus gtx card in the desktop did not boot up anything on the monitor at all.  The MSI gtx card pulled from the desktop, put in the core x, was discovered fine on the thunderbolt laptop.  

I'm glad I figured out its hardware and not waste anymore time chasing a non-existent software issue.  Thanks for all who replied.
