The Cpanel has a MySQL database.  When that is selected there is no option to edit.  Only a prompt to create or repair.  Superuser permission was confirmed with tech support. 

What else is important to SET GLOBAL TRANSACTION ISOLATION LEVEL READ COMMITTED; to fix the 'repeatable read' warning in Drupal's Status report?

Managed databases often limit an access to these low-level things.

In the documentation you've quoted there is and

The "Other methods to change the transaction isolation level" chapter. It contains an acceptable workaround by tuning the settings.php file, which works just fine.
