Z690 no onboard video output

hi i have a msi z690 unifi with no video out ports but the info on it says supports on board graphics if the cpu 12900k supports it. am i supposed to get a usbc monitor for this or what?
this pc is my server running proxmox. i have a 8600 gts but this very old graphics card.
i want to be able to use handbreak thru the intel gpu to encode av1 video.
i was going to get intel graphics card but i also would like that to be able to work with ai and seems nvidia is only ai graphics cards?
im thinking of going with a asus pro art or another suggestion if this will not work.
i also want to be able to put ai software on this and im getting no compatible gpu issues with that. even though i have neural accelerator detected on cpu.
