您的思路是正确的，但您需要知道样式表的ID。它不一定与样式表的文件名相同。

检查页面的生成源（即，在浏览器中加载页面并查看源）。查找<link> 正在加载样式表的标记。如果已将其正确地排入WordPress的队列，则它应该如下所示：

<link
 rel="stylesheet"
 id="your-stylesheet-id-css"
 href="https://example.com/path/to/your-stylesheet.css"
/>

因此，在我的示例中，您需要：

add_action( \'wp_enqueue_scripts\', \'wpse_382138_unload_css\', 9999 );
function wpse_382138_unload_css() {
    wp_dequeue_style( \'your-stylesheet-id\' );
}

参考文献wp_dequeue_style()

你的基本策略是正确的。问题是，尽管有一些最佳实践，但你永远无法百分之百地以简单的方式确定：

插件或主题将脚本和样式排队时hook your code to different actions when the scripts and styles are printed （和未排队）并测试不同的优先级。或者b）你可以检查每个插件和主题代码，看看每个插件使用了什么挂钩和优先级wp_enqueue_script 或wp_enqueue_style 呼叫

我建议选择选项a，比如：

    function wpse_382138_disable_plugins_style()
    {
        //these should use the same priority of later than the priority used by the plugin or theme when hooked
        wp_dequeue_style(\'stylesheet-handler-with-default-priority\');
        wp_dequeue_style(\'stylesheet-handler-with-explicit-default-priorit\', 10);
        wp_dequeue_style(\'stylesheet-handler-with-later-priority\', 20);
    }
    function wpse_382138_disable_plugins_scripts()
    {
        // these should use the same priority of later than the priority used by the plugin or theme when hooked
        wp_dequeue_script(\'script-handler-with-default-priority\');
        wp_dequeue_script(\'script-handler-with-explicit-default-priority\', 10);
        wp_dequeue_script(\'script-handler-with-later-priority\', 20);
    }

    // option A: hook your unhooking functions either to hooks later than wp_enqueue_scripts or wp_enqueue_style as wp_head or wp_footer.
    add_action(\'wp_head\', \'wpse_382138_disable_plugins_style\', 10);
    add_action(\'wp_footer\', \'wpse_382138_disable_plugins_style\', 10);
    add_action(\'wp_head\', \'wpse_382138_disable_plugins_scripts\', 10);
    add_action(\'wp_footer\', \'wpse_382138_disable_plugins_scripts\', 10);

    // option b: hook your unhooking functions to the printing actions with a priority lower than the before first scripts or styles are usuarlly written, so they will execute the dequeue before scripts and styles are printed.
    add_action(\'wp_print_scripts\', \'wpse_382138_disable_plugins_style\', 5);
    add_action(\'wp_print_footer_scripts\', \'wpse_382138_disable_plugins_style\', 5);
    add_action(\'wp_print_styles\', \'wpse_382138_isable_plugins_scrips\', 5);
