If you want to experiment anyway, options.programs?nixvim would return true when programs.nixvim exists as an option. (options can be loaded at the top of the file similar to pkgs and config.)

(Source: #178 (comment))

What about the following assertion:

Suggested change
config = lib.mkIf config.stylix.targets.nixvim.enable {
config = lib.mkIf config.stylix.targets.nixvim.enable {
assertions = [
{
assertion = options.programs?nixvim;
message = ''
'stylix.targets.nixvim.enable' is set to
${config.stylix.targets.nixvim.enable}, but the external
'options.programs.nixvim' dependency is unavailable:
https://github.com/nix-community/nixvim
'';
}
];

Note that I have not actually tested this.

With mkIf, evaluation still fails when the option doesn't exist, even if config.stylix.targets.nixvim.enable is set to false

The following should gracefully skip evaluation if config.stylix.targets.nixvim is not available:

Suggested change
config = lib.mkIf config.stylix.targets.nixvim.enable {
config = let
targets = config.stylix.targets;
in lib.mkIf (targets?nixvim.enable && targets.nixivm.enable) {

Note that I have not actually tested this.

programs.nixvim.colorschemes.base16.customColorScheme = let
colors = config.lib.stylix.colors;
prependHash = color: "#${color}";
in {
base00 = prependHash colors.base00;
base01 = prependHash colors.base01;
base02 = prependHash colors.base02;
base03 = prependHash colors.base03;
base04 = prependHash colors.base04;
base05 = prependHash colors.base05;
base06 = prependHash colors.base06;
base07 = prependHash colors.base07;
base08 = prependHash colors.base08;
base09 = prependHash colors.base09;
base0A = prependHash colors.base0A;
base0B = prependHash colors.base0B;
base0C = prependHash colors.base0C;
base0D = prependHash colors.base0D;
base0E = prependHash colors.base0E;
base0F = prependHash colors.base0F;
