从documentation:

要添加、删除或修改任何自定义程序对象，并访问自定义程序管理器，请使用customize_register 挂钩：

function themeslug_customize_register( $wp_customize ) {
  // Do stuff with $wp_customize, the WP_Customize_Manager object.
}
add_action( \'customize_register\', \'themeslug_customize_register\' );

Customizer Manager为每个Customizer对象类型提供add\\u、get\\u和remove\\u3种方法；每个都使用一个id。get\\uMethods允许在添加控件时直接修改指定的参数。

add_action(\'customize_register\',\'my_customize_register\');
function my_customize_register( $wp_customize ) {
  $wp_customize->add_panel();
  $wp_customize->get_panel();
  $wp_customize->remove_panel();

  $wp_customize->add_section();
  $wp_customize->get_section();
  $wp_customize->remove_section();

  $wp_customize->add_setting();
  $wp_customize->get_setting();
  $wp_customize->remove_setting();

  $wp_customize->add_control();
  $wp_customize->get_control();
  $wp_customize->remove_control();
}

因此，在您的情况下，可以使用WP_Customize_Manager::remove_control().

十九世纪主题示例：

function my_theme_customize_register( $wp_customize ) {
    // Remove the Colors -> Primary Color option.
    $wp_customize->remove_control( \'primary_color\' );
}
add_action( \'customize_register\', \'my_theme_customize_register\', 11 );
