nvidia - How can I switch between Nouveau and INTEL video driver?

On laptops with NVIDIA Optimus, Nouveau is installed by default.
When you try to install closed-source driver of NVIDIA, it's possible to switch between NVIDIA and INTEL video driver via NVIDIA's control center.

But what if I don't want to install the closed-source driver, will I be able to switch to INTEL driver from Nouveau? How?
