So I should make these changes right?

Sorry I did not understand clearly what should I do except these settings.

Kaby Lake
Support up to Ventura
Device Properties - Add - PciRoot(0x0)/Pci(0x2,0x0)
AAPL,ig-platform-id -> 00001B59
or:
AAPL,ig-platform-id -> 00001659

For UHD620 users (Kaby Lake-R), you'll need a device-id spoof:
device-id -> 16590000

kernel - quirks:
enable:
DisableIoMapper
PanicNoKextDump
PowerTimeoutKernelPanic

SystemProductName:
