How to dequeue wp_get_custom_css in Twenty Twenty Theme

How to remove Additional CSS from loading. It loads as internal style sheet on every page. I am doing this but it is not working. if I

print_r(wp_get_custom_css());
It shows the same css. I want to disable it to load.

add_action( 'wp_enqueue_scripts', 'mywptheme_child_deregister_styles', 11 );
function mywptheme_child_deregister_styles() {
    wp_dequeue_style( 'wp-custom-css' );
 
}

That style HTML is added by WordPress using wp_custom_css_cb() and it’s hooked to wp_head like so:

add_action( 'wp_head', 'wp_custom_css_cb', 101 );

Which adds the custom/additional CSS in the document head.

So if you don’t want that to happen — or you’d rather add/load the CSS manually, you can add this to your theme functions.php file:

remove_action( 'wp_head', 'wp_custom_css_cb', 101 );
