TryAdvisoryXactLock will try to obtain transaction-level exclusive lock. It will not wait for the lock to become available. It will either obtain the lock immediately and return true, or return false if the lock cannot be acquired immediately. If acquired, is automatically released at the end of the current transaction and cannot be released explicitly.
