This take a couple of steps, first hiding the title WP title field. I see that you’re also not using the WP editor so that makes it a bit easier

add_action('admin_head', 'hide_wp_title_input');
function hide_wp_title_input() {
  $screen = get_current_screen();
  if ($screen->id != 'your-custom-post-type') {
    return;
  }
  ?>
    <style type="text/css">
      #post-body-content {
        display: none;
      }
    </style>
  <?php 
}

next, update the post to use the custom title field for the post title

// you'll want to rename the function
add_action('acf/save_post', 'save_post_type_post'), 20); // fires after ACF
function save_post_type_post($post_id) {
  $post_type = get_post_type($post_id);
  if ($post_type != 'your-custom-post_type') {
    return;
  }
  $post_title = get_field('your_custom_field', $post_id);
  $post_name = sanitize_title($post_title);
  $post = array(
    'ID' => $post_id,
    'post_name' => $post_name,
    'post_title' => $post_title
  );
  wp_update_post($post);
}
