Hi,
>> render engine in AutoCAD 3D modelling?
Well, what's the real question? Searching for a setting for use of command _RENDER or while modelling, which are different...
To assign CPU or GPU for command _RENDER is not possible any more, it was a while ago, but not any more. It uses multi-cores of your CPU, but not the GPU.
To make more use of GPU while modelling you should set your drawing (your current viewport) to a visual style other than "2D Wireframe" ... that gives the graphic card more work for getting the display refreshed while modelling, zoom/pan/orbit ...
