Would they work if I install Game Ready driver and CUDA driver at the same time?

My laptop has a GTX960M and works with Windows 8.1 and Game Ready driver currently. I wonder what will happen if I install CUDA driver now and let them exist at the same time?
Will two drivers for one video card work properly at the same time? Like when I play GTA the Game Ready driver will work, and when I doing deep learning jobs the CUDA driver will work.
Or I have to switch between them and reboot the OS? Or there will always be conflicts and I have to keep only one of them?
Thank you for any advice.

You can’t have two GPU drivers installed at the same time.

Not possible.
