it seems to work!!!
the only problem I don't remember, because it was a long time ago, is the screen order problem.
my GPU has 3 video ports, 1 hdmi which I'm using and 2 displayports.
I simulated the presence of 2 other screens on the displayports only that the HDMI becomes screen 3 and not 1 so I don't see the windows I opened on screen 1. I have to move the windows with move...
I also need a CRU dump of one of your 4K monitors to simulate it. attach it.
probably in your case maybe it's not a problem because I understand that you disconnect the other screens.
new registry key to create is "EdidLockData"
for those who are reading what I wrote, I'm only talking about override edid not about crosflash between quadro and gtx/rtx gpu which is bullshit.
I think you can also try to do everything yourself, first examine the file carefully to see what you need to replace.
I used this edid because I didn't have yours, you have to export it with CRU and replace it.
this is my edid.

it's definitely not 4k, be careful when doing this there are 2, one per port.
for the output video ports I used a101 and a103 they should be the ones currently used by the monitors.
in case you want to replace them, don't forget the ones present towards the end of the file
if you have problems you have to enter safe mode and delete the key and everything goes back to normal.
