are AMD GPUs just plug and play?

I am getting a RX 6600 XT card for my hackintosh. According to Dortania guide on GPUs the Lilu and WhateverGreen kexts are required and my EFI already has them. Does this mean that the GPU is plug-and-play and will just start working after it's installed? (I may need to add a boot argument but that is a small detail that will only take a minute)
