How to change the saturation of the second monitor in a laptop?

Question

Monitors

I have a laptop and a monitor.
The laptop has an Nvidia graphics card.
There are drivers for it and the Nvidia Control Panel application.
This application has a tab with color saturation settings. Everything is great!
When I connect a second monitor, it no longer has this setting.
And no matter how I try, I can't reduce the color of the monica.
Let's just say that the lower the color, the closer to black and white everything goes.
Usually, by default, the saturation is 50%, for comfortable work for a PC, I need to set about 40%.
I did not find a single program in which it could. I would be very happy if someone can advise.
