See: How to Order Posts by Modified Date in WordPress

Add the following code showed below to the theme’s functions.php.

function themesdna_sort_homepage_posts_by_modified_date( $query ) {
    if( $query->is_main_query() && ! is_admin() && $query->is_home() ) {
        $query->set( 'orderby', 'modified' );
        $query->set( 'order', 'DESC' );
    }
}
add_action( 'pre_get_posts', 'themesdna_sort_homepage_posts_by_modified_date' );

You can edit the functions.php at Appearance>Theme File Editor:

If you encounter a fatal error and cannot access WordPress Admin Dashboard, you can connect to the instance and edit functions.php at /opt/bitnami/wordpress/wp-content/themes/blogus/functions.php.
