Hi ,
I am Ivan, I will help you with this.
Directx 12 ultimate is already enabled after you install your GPU drivers, it will be used so you can check by downloading GPU-Z from Directx Support (12_2) you are already using directx 12 ultimate.
Remembering that you have to have GPU scheduling activated to be able to use some of the DX12 functions, among others.
