I found an answer by myself:

1.

add_filter( 'wpcf7_load_css', '__return_false' );
add_filter( 'wpcf7_load_js', '__return_false' );

2.

function custom_jquery() {
  if (!is_admin()) {
   	
    wp_enqueue_script('jquery');
    wp_enqueue_script('jquery-migrate');

    // IF CF7 IS LOADED
    if (is_page('contact')) {
      wpcf7_enqueue_scripts();
      wp_enqueue_script( 'require-js', get_stylesheet_directory_uri(). '/js/require.min.js', array( 'jquery', 'jquery-migrate','contact-form-7' ) );
    } else {
      wp_enqueue_script( 'require-js', get_stylesheet_directory_uri(). '/js/require.min.js', array( 'jquery', 'jquery-migrate' ) );
    }
  }   
}
add_action('wp_enqueue_scripts', 'custom_jquery');

So there is an dependency for require-js, not for cf7.
This is not the best solution, for example there is another plugin, wich needs an deps, but if there is one in a projekt, I can add this too like this above…
