Is it possible to sort the post based on a custom field?

I have a custom field called "value_date" where I enter a date e.g yyyy/mm/dd

The idea is sort the upcoming dates first in the loop, is possible?

I used a template for custom post taxonomy-event-date.php

<!-- // The Query // -->
<?php
if( have_posts() ) {
$alt_post = 'alt-post';
while( have_posts() ) {
the_post();
$alt_post = $alt_post == 'alt-post' ? '' : 'alt-post';
?>
<div class="box-page-shows-block">
        <?php
        global $wp_query;
        $postid = $wp_query->post->ID;
        echo get_post_meta($postid, 'value_date', true);
        wp_reset_query();
        ?>
        </div>
        <h2><?php the_title(); ?></h2>
        <?php
        }
        }
        ?>

EDIT Not working only displayed one post Loop in template for custom post taxonomy-event-date.php

            <?php
    $args = array(
      'post_status'       => 'publish',
      'posts_per_page'    => 6,
      'paged'             => $paged,
      'meta_key'          => 'value_date',
      'orderby'           => 'meta_value_num',
      'order'             => 'ASC'
    );
    $query = new WP_Query( $args );
    if ( $query->have_posts() ) {
        while ( $query->have_posts() ) {
            $query->the_post();?> 
    <h2><?php the_title(); ?></h2>
<?php
                          
}
 }
wp_reset_query();  // Restore global post data stomped by the_post().
?>

Functions.php

add_action('pre_get_posts','search_filter');
function search_filter($query){
    if ( !is_admin() && $query->is_tax( 'event', 'date' ) ) {
        $query->set('post_status', 'publish');
        $query->set('meta_key', 'value_date');
        $query->set('orderby', 'meta_value_num');
        $query->set('order', 'ASC');
    }
}
