How to disable autocompletion on schema names?

When I double click the left side bar to enter a table under a schema, it automatically run two commands -- 'use SCHEMA_NAME' and 'SELECT t.* FROM SCHEMA_NAME.TABLE_NAME t LIMIT 501'.

How can I disable the autocompletion of the SCHEMA_NAME, which allow me can do this operation only by run command like 'SELECT t.* FROM TABLE_NAME t LIMIT 501'?

We have a db proxy in our company and it will go wrong when execute command with SCHEMA_NAME prefix.

Thanks for the help.
