Change Schedular for NixOs Zen kernel

Help

Change default schedular for NixOS-Zen kernel.
Well it’s not obvious and Syntax is very esoteric,
Here config which works,

# Gebruik de override direct bij de toewijzing om recursie te voorkomen
  boot.kernelPackages = (pkgs.linuxPackages_zen.extend (f: p: {
    kernel = p.kernel.override {
      ignoreConfigErrors = true;
    };
  }));

  boot.kernelPatches = [ {
    name = "zen-tuning-config";
    patch = null;
    structuredExtraConfig = with lib.kernel; {
      SCHED_ALT = yes;
      SCHED_BMQ = yes;
      SCHED_PROXY_EXEC = yes;
      BSD_DISKLABEL = yes;
      MINIX_SUBPARTITION = yes;
      SCHED_PDS = no;
    };
  } ];

Most important , ignore errors.
