I am testing with HP8100CMT i7-870 RX460 iMac11.3 OS10.13.6 OpenCore 0.6.6.
Currently I lost my audio (working on it, but still not clear why)and have the memory error in BigSur although I added and configured CustomMemory.plist.
I'm surprised you have Big Sur running.
Try deleting Root-> DeviceProperties-> Add-> PciRoot (0x1) / Pci (0x1B, 0x0).
Check if alcid = 13 in Root-> NVRAM-> Add-> 7C436110-AB2A-4BBB-A880-FE41995C9F82-> boot-args is correct.
If you set Root-> PlatformInfo-> Generic-> SystemProductName = MacPro7,1, a warning will be displayed every time because the memory configuration is different.
If iMacPro1.1 does not succeed, it seems better to check the basic operation with MacPro6,1 and then select another.
I hope that your goals will be achieved.
