Ran in to several roadblocks on this latest build and ended up getting nowhere. Any pointers would be appreciated!

Motherboard: Aorus H470I

CPU: Intel Core i5-10600K

GPU: RTX 3070 (I don't intend on using this for the hack but this is important)

I am dual booting: Windows 10 on an NVME SSD and macOS on a SATA hard drive. There are several other non bootable drives attached to the system.

Roadblock 1: I cannot get Windows to recognize displays connected to the iGPU over HDMI. After some testing, I discovered I could only get my display detected over the DP port on my motherboard. I had never tried using the motherboard video ports up to this point. This sucks because I only have one DP port on my monitor and I was hoping to easily switch between Windows and macOS without having to plug a bunch of things around.

Roadblock 2: I cannot get into my BIOS when my display is connected to the iGPU and not the dGPU. No matter how many times I spam F12 and Delete and End and F8, it boots straight to Windows. I never even see the motherboard splash screen. This is a huge issue because the only way to get into the BIOS is to connect my display to my graphics card, which means I can't boot macOS! There is also no option in my BIOS to set a preferred initial display output, which I find very odd.

Roadblock 3: Windows 10 is unstoppable. I cannot keep it from booting. Also, my Hackintosh installer just doesn't boot. I put my installer to the top of the boot order and tried that, booted straight to windows. Tried to avoid that by removing windows from the boot order entirely, hoping it'd at least go back to the BIOS. NOPE! Boots straight to windows anyway.

So I have literally gotten absolutely nowhere. Haven't even been able to boot my bloody install media. Hopefully I'm just missing obvious things. I've hackintoshed two machines before (admittedly one was just through Clover) and have never met this level of comical failure.
