I know there are some efi implementations that need pcie_ports=compat. I also know that sometimes you need intel_iommu or amd_iommu=off.
Those are local hacks to get very new or very exotic hw to work without fixing the kernel properly. But it's not the way this *should* work. Instead, the kernel should detect these systems properly on its own, and make this work without adjusting the kernel cmdline. There's plenty infrastructure for that available in the kernel.
What you are doing with the above is a hack that should require highest privileges to do, and hence it's OK (not just OK, it's *good*) to disable SecureBoot for that while you make them.
