You can press Win+P to choose which screens to enable.

Didn't think about RX 580 support of HDMI 2.1 Shy

I did all the changes, will take a look.

Noticed a weird monitor behavior - monitor darkens an output image even on th Win10 desktop but the cursor itself remains with previous brightness. Even if i increase brightness from the monitor menu it is still much darker and almost no brightness increase after that. Reboot helps to solve it. Maybe i didn't reboot PC after CRU manipulations, maybe i did some other changes, who knows Huh

That's a bug in AMD's driver with Polaris GPUs and not an issue with the monitor. It happens randomly when the driver loads if there's an EDID override. If it happens on boot, you can press Ctrl-Shift-Win-B to refresh the desktop.
