Couldn't Alloc Class 'AppleIntelPchSeriesAHCI"- Z390/ I9-9900K Install Error (Opencore)

Hi Everyone! This is my first build/install with any Hackintosh system and was facing the following error whilst installing Big Sur with OpenCore. After searching through some threads, was informed that there has to be a modified kext which was added but I keep on receiving the following error. My setup consists of the following:

Gigabyte Designare Z390
Intel I9-9900K
Radeon 5700XT
Samsung 970PRO SSD - M.2.NVE
HyperX Predator Black 32GB DDR Ram

Let me know if anything else is needed and...
