Macinabox Sonoma: GPU Passthrough

Hello guys, I am facing an issue at the very last part of the install of a macOS Sonoma VM created using macinabox: GPU passthrough. I got an RX 6800, since it's recommended by most of the community members. I dumped the GPU's vbios using SpaceinvaderOne's script. I also added agdpmod=pikera arg to the config.plist, and these arguments to the VM's XML: <qemu:commandline> <qemu:arg value='-usb'/> <qemu:arg value='-device'/> <qemu:arg value='usb-kbd,bus=usb-bus.0'/> <qemu:arg value='-device'/> <qemu:arg value='isa-applesmc,osk=ourhardworkbythesewordsguardedpleasedontsteal(c)AppleComputerInc'/> <qemu:arg value='-smbios'/> <qemu:arg value='type=2'/> <qemu:arg value='-global'/> <qemu:arg value='nec-usb-xhci.msi=off'/> <qemu:arg value='-global'/> <qemu:arg value='ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off'/> <qemu:arg value='-cpu'/> <qemu:arg value='host,kvm=on,vendor=GenuineIntel,vmware-cpuid-freq=on,+kvm_pv_unhalt,+kvm_pv_eoi,+hypervisor,+invtsc,+pcid,+ssse3,+sse4.2,+popcnt,+avx,+avx2,+aes,+fma,+bmi1,+bmi2,+xsave,+xsaveopt,+rdrand,check'/> </qemu:commandline> As a result, I only get a black screen.
