Yoast hooks

Hi,

Is it possible to get a list of hooks in order to disable features of Yoast ?

We are improving the performance of a website and we have found 1.000.000 (1 million) of useless postmetas.
We have deleted but we do not want them to be created again so we decided to code a plugin to do it.

We have already located some snippets but probably there are more hooks we could use to get better performance.

Now we have these scripts

function yoast_seo_admin_user_remove_social ( $contactmethods ) 
{
	if ( class_exists('WPSEO_Options') )
	{
		unset( $contactmethods['facebook'] );
		unset( $contactmethods['instagram'] );
		unset( $contactmethods['linkedin'] );
		unset( $contactmethods['myspace'] );
		unset( $contactmethods['pinterest'] );
		unset( $contactmethods['soundcloud'] );
		unset( $contactmethods['tumblr'] );
		unset( $contactmethods['twitter'] );
		unset( $contactmethods['youtube'] );
		unset( $contactmethods['wikipedia'] );
	}
	return $contactmethods;
}

add_filter( 'user_contactmethods', 'yoast_seo_admin_user_remove_social', 99 );


function rkv_remove_columns( $columns ) 
{
	if ( class_exists('WPSEO_Options') ) 
	{
		unset( $columns['wpseo-score-readability'] );
		unset( $columns['wpseo-score'] );
		unset( $columns['wpseo-title'] );
		unset( $columns['wpseo-metadesc'] );
		unset( $columns['wpseo-focuskw'] );
		unset( $columns['wpseo-links'] );
	}
	return $columns;
}

add_filter ( 'manage_edit-product_columns', 'rkv_remove_columns' );

Many thanks in advance
