Assuming that your posts do not have the field end

add_filter('acf/fields/relationship/query/name=main_feature', function($options, $field, $post_id) {
    $options['post_status'] = array('publish');
        $options['meta_query'] = array(
            'relation' => 'OR',
            array(
                'key' => 'end',
                'compare' => '>=',
                'value' =>  date('Y-m-d H:i:s'),
                'type' => 'DATETIME'
            ),
            array(
                'key' => 'end',
                'compare' => 'NOT EXISTS'
            )
        );
    return $options;
}, 10, 3);
