I do not know if this will work, it is purely a guess based on what I know

add_action('acf/init', 'check_acf_get_field_group_posts_cache', 20);
check_acf_get_field_group_posts_cache() {
  $cache_key = acf_cache_key("acf_get_field_group_posts");
  $post_ids = wp_cache_get( $cache_key, 'acf' );
  if ($post_ids !== false && empty($post_ids)) {
    // not false which should be returned for an empty cache
    // but empty, indicating an empty array
    // delete the cached value
    wp_cache_delete(acf_cache_key("acf_get_field_group_posts"), 'acf');
  }
}
