How to switch video card?

Question

Video cards

The laptop has an integrated and discrete vidyuha, integrated in short sucks than discrete, how to change it? I checked in the task manager and it was written that the one that is better is used, however, looking at the screen parameters, I realized that the one that is weaker is connected to it. I tried using the NVIDIA control panel, set the use of a high-performance processor, it did not help. I wanted to disable the integrated one in device manager, but didn't want to risk it because I'm a rather unlucky person. I tried through the bios, but I did not find the necessary parameter for changing the video card. In short, I need a discrete one to work, if you need screenshots for a more accurate understanding of what is happening to me, write below. Thank you!
