Tried clearing CMOS no luck there.Ok so do one of two things.
Either Shut down the system and pull all power and then open her up and short the bios to clear it or even better remove the cmos battery and wait a few minutes then put it all back together and reload your settings or and probbaly the better option is reflash your bios and see if it resets it. (That will probbaly do the trick)
This doesn’t work on nVidia GPUs. They hang on a black screen.
LoL I thought he was using a big Navi, I’m talking to too many people at once and mixing up who’s got what.
To boot Big Sur you'll likely need SSDT-CPUR & SSDT-EC-USBX-DESKTOP.aml in ACPI, OC 0.6.9, Lilu, Whatevergreen, AppleALC, VirtualSMC, USBPorts.kext and SMBIOS iMacPro1,1. No need for boot-args other than alcid for your soundcard.
For the Aquantia you could try this. Your PCIRoot settings may differ so add it in Devices using the + button:

Btw that device-id is this: 4b00000001000000010000003f0000000100000002010c00d041080a0000000001010600041c0101060000007fff0400160000006200750069006c0074002d0069006e0000000500000001
And the last bit for model says Aqtion.
I see. The app I used to show the Device Properties is Opencore Configurator. For the PCIRoot path for the Aquantia I'd suggest try using Hackintools.Thanks Middleman
Haven't got that far on big sur yet but will make sure all those are included on full attempt.
--I have to get it to boot into installer and install all in VirtualBox first so I can add Nvidia drivers, but VirtualBox going to take some time since it gets stuck when I use USB somewhere in early boot so I will try next to make USB map to an internal sata drive so maybe it gets past that point were it is getting stuck, which i think is when it loads usb drivers.
For the Aquantia I am still a little noob like here, what app are you using to do the + button on PCIRoot?
--I have DPCIManager and can see the Ethernet controller in PCI List but not sure how to get PCIRoot path to add to config.plist.

Hey @CoolBean, thanks for making this post. I have a similar setup with X570 AORUS Elite Wifi, X5950 and 1080 Ti. Could you please share your most up to date EFI? I tried starting from scratch but am getting stuck during boot. Also, can you post what BIOS setting changes you made for macOS? Thanks!
oh, I thought you got a working version of High Sierra on X570 with 1080 ti? I'm not looking to run Big Sur since I need the Nvidia web drivers for my 1080 ti. do you have a working EFI for High Sierra? I'll take whatever you got as a starting point. thanks!Still stuck on boot with Big Sur :
Virtualbox : Cant get past screen right when text should change resolution so I think its having trouble with 1080 in emulation also.
--Same in Mac OS 10.13.4 or in Windows 10, I guess Virtual box uses a similar version to your graphics card so still need drivers, was hoping it was emulating a generic card.
Direct Install of USB with OpenCore:
I can boot into installer and get initial install complete/Format drives/Safari/Restore.
Howerever Big Sur on initial install just puts the base on target drive, then reboots using that drive as boot drive.
-- This is were I get stuck since I believe it needs Nvidia drivers installed as first half screen of text fills and then instant reboot.
If I could just figure out a way to get it to not try to load custom graphics drivers and just use same generic graphics drivers used in installer I could get Nvidia graphics drivers installed.
--I tried -x for safe boot but did not work.
--I tried -no_compat_check to stop it from checking to see if its support configuration for Big Sur but did not work.
I think we may just need to get a compatible graphics card to install the OS then install Nvidia drivers and then put the 1080 back in.
