Not really. Deadlocks are avoided by disciplined programming practices.

Deadlock requires stremlining your data access. You can control your job but cannot control other areas in the Org that will lock the db.

Isolation levels are ansi standard mechanism to handle data access.

Those configurations are set by your DBA. Ask your DBA for the answers.
