How to upgrade a MacBook without a GPU?

Hello! I have a 2011 MacBook Pro, and the graphics card is faulty. That's why we disabled the graphics card. I want to install Big Sur or Monterey using OpenCore, but when I do, there is about a 20-second delay with the keyboard and mouse. When I move the mouse, it gets detected after approximately 20 seconds. However, the system animations work fine, so the issue is with detecting the inputs. Is there a solution for this?
