How can I trigger a Yongnuo YN-568 off-camera on a Nikon D750 with TTL and high-speed sync without using the built-in flash?

I’m using a Nikon D750 and want to fire a Yongnuo YN-568 flash off-camera with TTL and high-speed sync, but I don’t want to rely on the camera’s built-in flash as the optical commander. What setup do I need to keep TTL/HSS working, and does it matter whether the flash is the Canon or Nikon version?

I'm kind of confused by your question. The YN-568EXII is Canon-only. There is no Nikon version. And e-TTL is Canon's flavor of TTL. The Nikon version is i-TTL. If you're trying to shoot with Yongnuo's for-Canon gear with a Nikon camera, you cannot get TTL or HSS on the hotshoe or on radio triggers. You can only get TTL and HSS through CLS (Nikon's "smart" optical slaving system). The TTL and HSS communication protocols are proprietary and brand-specific, and you'd need to use the YN-568EX for Nikon (it will have gold lettering on it, not silver). The Canon gear only gives you eTTL and HSS with a Canon camera and Yongnuo's 622C triggers.
If you are shooting with a D750, you need the Yongnuo 622N triggers (or other iTTL-capable triggers) and the for-Nikon Yongnuo YN-568EXs (Mark I) to maintain iTTL and Auto FP (HSS) communication.

Yes, it matters. Nikon uses i-TTL, while Canon uses E-TTL, and those systems are brand-specific. If you have the Canon-only YN-568EX II, you won’t get TTL or HSS with a Nikon D750 via the hot shoe or radio triggers.
For a Nikon D750, you need the Nikon-compatible YN-568 version and Nikon-compatible triggers. A common Yongnuo setup is:
- YN-622N-TX on the camera as the transmitter
- One YN-622N receiver on each flash
- Nikon-compatible YN-568 flash units
This lets you use off-camera flash with Nikon i-TTL and high-speed sync without firing the built-in flash at your subject. The 622N-TX is generally easier to use as a transmitter because it has an LCD screen, while a regular 622N can also act as a transmitter but is less intuitive.
If you only use Nikon’s optical CLS system, TTL/HSS can work, but that depends on line-of-sight and still uses optical signaling from the camera/pop-up flash system.
