1. You can use pre_get_comments hook:

add_action(\'pre_get_comments\', function($query)
{
    global $pagenow;
    if ( is_admin() && (\'your-custom-page\' === $pagenow) ) {
        $query->query_vars[\'meta_query\'] = [
            \'relation\' => \'AND\',
            [
                \'key\' => \'key1\',
                \'value\' => \'meta1\'
            ],
            [
                \'key\' => \'key2\',
                \'value\' => \'meta2\'
            ]
        ];
    }
});
