Implement gameworks suite in UE4

Hi, It is my understanding that in order to implement nvidia gameworks suite into a game development that I can not do this with official unreal engine 4 and need a child branch version of unreal engine 4. Is this correct? I am a cuple months into game development now and just now started to think about gameworks. I am using the latest UE4 from epic 4.20, so in order to implement any gameworks, my only option is to start completely over from beginning with a version of unreal engine 4 that supports this? I just want to make sure I am understanding correctly and that there is not some other option I am missing. thank you!
