How to disable some nvme disks on a PCIE<->M.2 adapter

[xjzhang1979]

Hi there, I have a PCID<->M.2 adapter with four nvme disk, but two of them cannot be recognized by Mac.
I found some post that can disable the unspported nvme disk by modifying SSDT file.
Their example pci path likes: ACPI(_SB_)#ACPI(PCI0)#ACPI(GPP0)#PCI(0000) and they use "_SB_.PCI0.GPP0" in the SSDT file.
But my case is as following which has two PCI parts
ACPI(_SB_)#ACPI(PCI0)#ACPI(GPP0)#PCI(0000)#PCI(0000)
ACPI(_SB_)#ACPI(PCI0)#ACPI(GPP0)#PCI(0040)#PCI(0000)
ACPI(_SB_)#ACPI(PCI0)#ACPI(GPP0)#PCI(0080)#PCI(0000)
ACPI(_SB_)#ACPI(PCI0)#ACPI(GPP0)#PCI(00C0)#PCI(0000)

I want to disable the first two disk; I use "_SB_.PCI0.PEG0.PEGP.0400" in SSDT file, but it reports error.
How should I modify the SSDT file?

Overview The purpose of this guide is to explain how to use the class-code spoof technique to keep un-patched IONVMeFamily.kext (incompatible with most PC NVMe SSDs) from loading such that HackrNVMeFamily can be used along side it in EFI/Clover/kexts or installed to the system volume...
