Windows 10: Force "duplicate these displays" setting to be persistent.

I am using two outputs from the motherboard's onboard graphics, the HDMI and the VGA.


The VGA is powering a single monitor on the rack and the HDMI is going to a 4-way splitter that powers 3 additional displays.


Somehow the setting changes itself from "duplicate" to "extend", resulting in the HDMI displays showing an empty screen. I suspect this happens when someone randomly turned off all the HDMI screens.


How do I force the setting to stay, even if all the monitors are off or even disconnected. I want there to be no possible way that it accidentally gets switched.


Thanks!
