A40 acceleration for Gaming/Rendering

I have an array of A40s that im using for different tasks and on Win 10 Pro i am using them as a workstation GPU for rendering and programs like UE5. I am wondering how i optimize them for that task and tasks like it… basically i need to bring those RT cores into operation.
On a side not currently i have 6 A40s and when i turn on SLI it freaks out and sometimes crashes windows.
