I do not know if this will work or not because I have not actually tried it. The reason that the post is not saved in revisions is that the post is not actually being updated, only the custom fields are. You need to cause WP to update the post so that it saves a revision.

What I would try is to create an acf/save_post filter. I think that you would need to do this on a priority of < 10 to that the revision is created before the fields are updated, but I am not 100% positive of this. I would try < 10 first and if that does not get the results you are looking for than try > 10

add_action('acf/save_post, 'force_revisions_save', 1);
function force_revisions_save($post_id) {
  if (is_admin()) {
    // not needed in admin
    return;
  }
  $post_type = get_post_type($post_id);
  if ($post_type != 'YOUR POST TYPE HERE') {
    // only run on your post type
    return;
  }
  // get the post
  $post = get_post($post_id);
  // remove this filter to prevent infinite loop
  remove_filter('acf/save_post, 'force_revisions_save', 1);
  // update the post
  wp_update_post($post);
  // re-add this filter
  add_action('acf/save_post, 'force_revisions_save', 1);
}
