I don’t think you’ll be able to do this blind. There seems to be some variation in how BIOS is set up across Nuc builds. So you’d likely need to find someone with the same version of Nuc who is also willing to go through the whole setup sequence again.
As @bearFNF suggests, your best bet is an HDMI cable to the TV.
As others have said, you’ll need a keyboard (and ideally a mouse) for the initial bios setup and rock installation. Hdmi to your tv can be a substitute for a screen.
Good luck! Using rock myself - once you’re past the initial setup you probably won’t need a screen, kboard or mouse ever again
