Windows 10: Changing display numbers

I am not sure where to ask about this, but...........
I have an Asus dual GTX 1060 and 2 monitors. #2 is connected to the DVI port and #1 is on the HDMI port.
#2 is my default monitor. With Windows set to extend the monitors, when the system boots, the boot screen appears on monitor #1, then everything runs on #2.
How can I make the boot screen appear on #2?

I can find nothing in the NVidia control or Windows control to do that.
I am assuming the reason #2 cannot be made #1 is that it is defined by the port it is plugged into.
I am not talking about setting right/left monitor. I want identify to show 1 on my default monitor that now shows 2.

Or I would be happy with making the boot screen show on #2.

The MB is an MSI MPG x570 Gaming Plus.

Previously, with my old MB, the boot appear on #2, so is it a MB issue?

Windows 10 - Change Display Numbers / Identity

I can get to the display setting where I can re-order displays:





But is it possible to actually re-number them as well?

The reason simply re-ordering doesn't fit my use case, is because other applications, like Skype, will use the original numbers and locations, which leads to some counterintuitive selections





All of these threads just suggest using display settings to shuffle monitors around:

Recent (Save Files) - Change Default Settings to OneDrive

Hello -
Thanks for the return. Before I undertake changing the Registry, I have a question.
The steps in my Registry, for my version of Windows 10, were a bit different, but I think I eventually got to the right spot.
The last step is to change the number of places you want to list in Recent Places. In my case, the default Max Display listed 50 as the number. So, if I were to change that number, how do I know the Save As page will be one of those places? Or, a similar question, will this registry change delete the tab Recent from my Save As page? This is what I would like to happen.
When I received my computer in Nov. 2016, the Recent tab was not listed in the Save As page. Something caused it to be added over time. Which brings me to this second question. Would there be any benefit in deleting the changed registry listing and reverting back to the default listing? See attachment.
