It doesn't show, I seated the card on the second to last pci-e x4 slot.
Only my SB x-fi shows up on that pair (a1/a2 in 4x4x). And all pci-e is set to gen3.
Allthough Windows sees the card, can install on it but not selectable as boot device in the bios.
 

You don't need to select is as a boot device. With CSM disabled, it will automatically boot to the SSD. I have my boot device order all set to "disabled".  Try removing the X-FI card and see if it works. You can see my specs in my sig, I am having 0 issues booting off of my 750. I am also using BIOS 2.13

Okay and thanks, it's visible in the bios now.
Seems mixing pcie gen 1 and 3 in one channel doesn't work.

Sadly, after installing W10 from usb ... either usb boots again or when it's removed, bios comes up.
- did set boot device order to disabeled
-removed all but vid card and 750

Do you have CSM disabled?

Yes I did disable CSM.
Makes me wonder why the bios keeps popping up instead of a bootdevice not found error or something like that.

The boot device not found error will only show up when you are running legacy mode as opposed to a uefi boot. The BIOS is popping up because it cannot boot from the drive for some reason, and the only logical remaining boot "device" is to return to BIOS. You may have a defective drive. Its very odd that you cannot boot from it. I suggest trying it one more time. Plug in your Win10 installer USB, run the install, when it gets to the point of needing to restart, hit "yes" and unplug the USB. It *should* boot from the SSD at that point. 

I did some more examination on nvme support in the bios and found out that technically nvme just should not work at all.
There's just  no support at all. EVGA might updateted eufi to 231 but has not implemented a driver for nvme.
 
Here a mmt tool report of evga x79 dark bios 2.13:

Interesting findings. Any of the EVGA techs/reps care to comment? I mean...my NVMe drive is working fine, it boots fine and shows up as NVMe in windows. Read/write speeds are spot on too. 

NVME is supported in UEFI only, it is not supported in Legacy mode, this is why the CSM version is an older version.
