How to enable a disable monitor?

Hello, I've got a 9 multimonitor system, 3X Nvidia GPU + 3X Usb UGA-165

I have disable the 8 of them, but now Win10 doesn't appear to me any of the disable monitor in "Display Settings",
I have re-enable the 5 of them using the Nvidia Control panel but I can't re-enable the Usb monitors cause they don't have control panel and Nvidia control panel doesn't control them.

The problem is that Windows "Display Settings" have remove the disable monitor, so is there any trick or registry setting that can change that?
As you can see there are missing monitors 6
, 7 and 8.

Thank you

Nevermind, I found a way to open old display settings

Win+R
control.exe desk.cpl,Settings,@Settings
