Custom Resolution Utility (CRU)

I have an InnoCN 27M2V, 3840x2160 monitor with up to 160hz refresh rate and G-Sync compatibility.
For many years now, I have been using CRU to strip my monitor's EDID of all refresh rates except the native peak one I like to run that allows me to avoid DSC.
This monitor for me, with HDMI 2.1, can handle 160hz but I actually want to defer to 144hz instead.

The problem is I cannot set the Detailed Resolution to 3840x2160 144hz because it is too high of a pixel clock. That means 60hz is the default native refresh rate of the panel.
Moreover, when I strip it of all other refresh rates and resolutions so the only two in the EDID are 3840x2160 60hz in Detailed Resolutions, and 3840x2160 144hz in DisplayID 2.0 block, the 144hz refresh doesn't show up at all. I have to add a custom resolution in the Nvidia Control Panel to get it.

This is annoying because any game that doesn't default to native resolution will trigger a signal swap to 60hz until I change resolution to native. And with this buggy monitor, every time there's a signal swap it stops applying every single setting in the display, forcing me to go back in and toggle them back and forth to get them to apply again, every time this happens.

Is it possible to only have 3840x2160 144hz in the EDID so it's the only refresh rate with a native resolution of 4k? Or is this a hopeless cause limited to older generation, lower resolution monitors?

You have to show me what you're doing because what you mentioned should work. Export a file with the changes and post it here.
