Opencore defaults to wrong display, any way to force a default?

So I'm a digital artist and I rely pretty heavily on Luna Display (hardware) and Astropad (software). Luna Display is a hardware dongle that connects as a "display" to displayport and then syncs that signal with the iPad to give you full GPU accelerated screen output unlike Sidecar. It also has some other major artist-driven features that Sidecar is missing.

My problem is that when the dongle is connected the computer defaults to the dongle and NOT MacOS. I'm curious if there is a way to designate a certain output as "default" either in BIOS or in Opencore. Any input is greatly appreciated!

I have the following hardware:

  • Asrock Z390 Phantom Gaming ITX
  • 9900K (No O.C.)
  • Powercolor Red Dragon 5700 XT
  • iMacPro SMBios (no need for Sidecar)
  • Opencore 0.5.5
