css – How to dequeue styles coming from plugins?

I’m trying to reduce the overloading by not to load all style sheets on my website’s homepage.
Some of those sheets is coming and loading from external plugins like woo-commerce,
I have tried to do that using `wp_dequeue_style` function, but it haven’t worked, those style sheets still being loaded!

For example, the first one is 100% not used:

When I use the code below:

function disable_plugins_style()
{
    global $wp_styles;
    wp_dequeue_style('style-rtl');
    wp_deregister_style('style-rtl');
    unset($wp_styles->registered('style-rtl'));
}
add_action('wp_enqueue_scripts', 'disable_plugins_style', 9999);
add_action('wp_head', 'disable_plugins_style', 9999);

It didn’t cause any affect, could I find someone can help me please.
