Is it possible to use the integrated Intel graphics on a PC if the monitor is connected to a discrete nVidia graphics card?

Question

Iron

Goal: debugging an OpenGL application on different video adapters, in my case, on the built-in Intel HD530 and on nVidia 1050.
Task: to switch between video adapters programmatically, without poking wires, and even more so without pulling out a discrete video card from the system unit.
All instructions found for switching between Intel Integrated Graphics and a discrete card seem to apply to laptops. I have not found an answer anywhere to the question of whether it is possible in principle to use Intel graphics in cases where the monitor is plugged into a discrete video card on a regular PC. Processor: Intel i3-7100 Motherboard: Asus PRIME B250M-K Video card: nVidia GTX1050 OS: Debian 10, but a Windows solution will work if available

Answer 1

OS: Debian 10

No.
Even with cable poking, there will be very big problems, for example, I did not manage to get two adapters to work simultaneously.
In theory, you can try to pick bumblebee, but the chances of winning tend to zero.

Answer 2

Bumblebee is a solution that allows you to use NVIDIA Optimus in GNU/Linux laptops, which includes two graphics adapters with two different power profiles using a common framebuffer.

if your cards don't support Nvidia Optimus, obviously you won't be able to switch soft.
