Drupal - What are my alternatives to disable update notifications but without using module Update Notifications Disable?

The method below will stop the "available update" emails Drupal admins receive.

1. Go here: http://yourwebsite.com/admin/reports/updates/settings

2. Remove your email(s) from the textarea: "E-mail addresses to notify when updates are available"

3. Save

Note: If you want to stop the "available updates" emails and the update alert messaging then simply disable the update module from http://yourwebsite.com/admin/modules

You can disable the module Update in the module list, but you will never be aware about update and security updates.

you can do it with drush:

drush dis update
