It seems that a bunch of these are just enabled by nixpkgs by default... I guess the solution is to simply = lib.mkForce unset all of these? Does not seem very elegant...

Nope, = lib.mkForce unset does not work for everything because apparently it cannot override non-modular configs like this: https://github.com/NixOS/nixpkgs/blob/798e8fcf0ea3f571cdc664869bf81d5aa69a38ef/lib/systems/platforms.nix#L366

I see two paths forward:

• Switch away from using johan_defconfig and use the modular config system to enable everything needed for x1e. As long as kernel compile times don't go up too much this should be fine. We could even try upstreaming the x1e support enabling to nixpkgs, stock upstream kernel should already be working well enough and provide basic functionality on x1e.
• Try to get a much more minimal kernel config, as proposed in Slim down kernel config by removing unnecessary drivers and modules #26. I could see both the "fat" and "slim" kernel configs having uses, one for being well integrated with upstream nixpkgs and one for quick iteration/testing.
