Can't get Nvidia Quadro K600 to work in Catalina

I installed Catalina 10.15.7 on my Dell Optiplex 9010 using Opencore 0.6.2. However the dCPU (Quadro K600) is not recognized. I thought Catalina has native support for the K600. Am I missing something? The link is my config.plist https://we.tl/t-2LBsWEExYF. If anyone has any suggestion, i would really appreciated. Thanks.
