I use the MySQL 8.0 to 5.7 backport database driver module to use MySQL 5.7 in a Drupal 11 site. Do I need to uninstall this module before the platform upgrade to MySQL 8.0?

Drupal 11 requires MySQL 8.0 or later. However, if your application uses MySQL 5.7 and you want to upgrade to Drupal 11, you can use the MySQL 8.0 to 5.7 backport database driver module. For more information, visit MySQL 8.0 to 5.7 backport database driver for upgrading to Drupal 11.
