2 Graphics cards in one system

Hii Everyone,
I have Dell system in that I am using rocky Linux 8.8, I want to use 2 graphic cards in that system for rendering purpose is there any possibility, we can do this process.

  1. Is there any application to use 2 GPU cards?
  2. Is there any device to connect both the GPU cards?

Running SLI or Crossfire should be entirely a function of the driver for your GPU. Consult the documentation for the manufacturer of your choice (NVidia/AMD).
