If you are not using those features then the vulnerability may be mitigated by stopping DAS.

To stop DAS, you would need to have DAS administration authority.
1. Log in as an account or user ID that is part of the group defined in the DASADM_GROUP parameter.
2. Stop the DAS using the db2admin command as follows:
db2admin stop
