How to hide blog by id wordpress multisite listing

How about an if statement?

<?php 
    $blogs = get_last_updated(' ', 0, 3); 

    foreach ($blogs AS $blog) {;
    switch_to_blog($blog["blog_id"]);

    $lastposts = get_posts('numberposts=1&orderby=date');
    foreach($lastposts as $post) : setup_postdata($post);
?>

<?php if $blog["blog_id"] != 1 { ?> // Run the Output if the ID is not X

    <div class="col-sm-4 blog-newest">

    <!-- blog name -->
    <h3><?php echo $blog_title = get_bloginfo( 'name' ); ?></h3>

    <!-- Link to blog -->
    <a href="https://wordpress.stackexchange.com/questions/251389/<?php echo get_page_link($post->ID); ?>"> 
        <?php echo $post->post_title; ?>
    </a>

    </div>

    <?php               
        endforeach;
        restore_current_blog();
    }
    ?> 

<?php } ?>
