Removing feeds from header using a function?

I want to remove the default RSS feed, which I can successfully do by adding this in functions.php file.

remove_action( 'wp_head', 'feed_links', 2 );
However, It is important for me to use this in a function instead of using directly. For that purpose, I’m trying following:

function remove_rss() {
    remove_action( 'wp_head', 'feed_links', 2 );
}
add_action('wp_head', 'remove_rss');

but that does not work. I think the reason is the wp_head loads after the feeds are loaded in the header. How can I make it load before the header adds the feeds? Thanks.
