PCIDriverKit Entitlement for Thunderbolt devices

We build Thunderbolt hardware, but at a PCI level they are generic so we do not have a PCI VID. They do require a kext driver. Currently Apple requires a PCI VID to get a PCIDriverKit entitlement. Is there any way that this requirement could be relaxed?

Full access to IORegistry in DriverKit

What is the best way to have full access to the IORegistry (traversing fromPath etc) from within DriverKit?IOService SearchProperty isn't enough control for the matching that I need to do. I also cannot work out how to change arbitrary IOReg keys from within my driver.
