Chris (crazychris) added a comment to T52191: CUDA support disappears when plugging in external GPU.

After playing around with this setup now for a day I just found this link
https://egpu.io/forums/implementation-guides/dell-precision-7510-akitio-node-galax-gtx-1080-hof-its-working/
where the user disabled the internal nvidia GPU and then the external GPU worked in CUDA-Z (!)
... and now it works in blender too!
(not a perfect solution but at least I didnt buy the Akitio +1080Ti for nothing - and maybe nvidia can fix this in the future)
PS: THX brecht for your help!

Yes, drivers are from nvidia. Control panel shows version 384.94
BUT Cuda-Z says "no compatible CUDA devices found" when the external gpu is plugged in :-(
... but nvidia gpu monitor shows eg Chrome running on the GPU (???)
any ideas?
