I have same problem on my old laptop. HCL - ASUS TUF Gaming A17 FA707RC . I not solved it, but maybe you can. How i understand hdmi connected to nvidia card, and still not working while you don’t use external gpu. I install nvidia drivers and create custom xorg file, then my external display start working.
I have same problem too. To fix it on install i choose set sys-net and sys-usb as one qube, and delete flag “makes it disposable”
I hope it helps. Luck for you
