Sort As By Date Of Publication As By Update

I'm setting up an Index and I'm trying to do the following ... I'm going to have this 'mini highlight' and at the moment I was able to sort it for DATE only, but sometimes the news will be updated and I would like this news to rise based on TBM on the modification date. Here is the code for you to analyze!

<div class="news-wrap" id="news-section">
                        <div class="row">
                            <div class="col-md-4">
                                <section class="news">
                                    <h4 class="section-title">
                                        <a href="<?= get_site_url(null, 'category/eventos-e-lazer') ?>" target="_self">Eventos</a>
                                    </h4>
                                    <?php

                                    $posts = get_posts(array(
                                        'numberposts'   => 4,
                                        'post_type'     => 'post',
                                        'category_name' => 'eventos-e-lazer',
                                        'orderby'       => 'date',
                                        'order'         => 'DESC'
                                    ));

                                    $count = 0;

                                    foreach ($posts as $post):

                                        setup_postdata($post);

                                        if($count == 0): ?>
                                            <article class="news-destaque">
