My first hackintosh is a success...sort of. What can I do if I forgot something?

I got Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina running on my Dell Laptop and it feels good. However, the keyboard and trackpad on the laptop doesn’t work. I have to use a USB keyboard instead. I think that this is because I missed adding the VoodooPS2 kext. Is there anyway I can add that in now or do I have to reinstall from the beginning with the kext thrown in?
