In CONFD we need to keep the cdb and NMS database in sync.This is an overhead.Is it possible to have confd with out cdb?We don’t want to add another database. That just creates another area where data can be out-of-sync.

You have the option to use the external database API as described in Chapter 7 in the ConfD User Guide to store the configuration data in an external database instead of CDB.
