add_action('customize_controls_print_footer_scripts', 'customize_themes_print_templates');

This example removes the function from the ‘customize_controls_print_footer_scripts’ action.

remove_action('customize_controls_print_footer_scripts', 'customize_themes_print_templates');

Check if function exists

This example checks if the function exists before calling it.

if (function_exists('customize_themes_print_templates')) {
    // Function exists, so print the JS templates for theme-browsing UI
