NIGHT SHIFT issue on Mac Pro with 2 external monitors

Hi, I have issue with my Mac Pro (6,1/6c/16GB/D500/256GB) and two external monitors(1-PHILIPS BDM4065uc and 2-EIZO EV233W). The issue is that when I startup with only main monitor (1), there is no Night Shift (NS) switch in Preferences/Displays or in the Notification center, BUT the colors on the monitor are WARM! Even though I did not able NS and restart/power up from state where NS was turned off. But when I turn on second monitor(2), the NS switch magically show up in Notification Center AND in the Preferences/Displays/EV2333W window (but still not at PHL BDM4065). So I switch on nad off the NS to get normal (colder) colors on both monitors.

BUT when I turn off the second monitor(2) I get warm colors on my main monitor(1) back and the NS switch disappear!!!

note:

I definitelly don't want NS function at all. I'm working with videos and I don't need any color changes since I made color calibration on both monitors..

Have some of you experienced something familiar or does anybody work out any solution (terminal command for disabling NS etc.)..?

Thanks guys.
