                ez-capi:
                    requires: ['capi']
                    path: /js/external/ez-capi.js

If everything is still relevant, then this is done very simply. A bundle that wants to modify the configuration of another bundle must implement the PrependExtensionInterface interface. And then in the prepend method we simply call

public function prepend(ContainerBuilder $container){
        $name = 'your_bundle_name'; // по конфигу видно что это system
        $config['default']['yui']['modules']['some_module'] = []; // конфигурация вашего модуля
        $container->prependExtensionConfig($name, $config);
}
