Yup, mandatory so far. The Clover folks like so many others are working on how to be able to use the new cards as the main screen during boot-up, but for now, it is not an option.
I think if you go back far enough, you will find that Gigamaxx and others have mentioned needing to do so but lately the problems have been more towards isolated problems than for overall start from scratch problems. IIRC, not all of the ID numbers are okay to swap for your ID, scroll back some pages, to see what the latest information is.
But here is one overall idea:
Make sure the hardware (BIOS) is set up, for now IGPU or IGD or ... IS needed.
Depending on the card you need to set up Clover differently, with still some possible kext editing. Fix permissions, update caches as needed.
It sounds like juanjullian is volunteering
maybe the moderators can assist in that direction.
