How to use an existing xorg.conf, rather than a nixos-generated one?

I imagine you can override that with services.xserver.displayManager.xserverArgs = [ "-config" <config> ]

You can try prepending with lib.mkBefore and completely overriding with lib.mkForce too, I think.

I wonder if there is a defined precedence.

It seems from a quick test that X uses the later definition of config. So by using lib.mkAfter instead, I was able to point to the existing xorg.conf within my filesystem. And with that manual config, I was finally able to get an output from my eGPU (or at least I was able to get my monitor connected to my eGPU to display a screen)
