Sm log KM errors

Experts,

Am setting up knowledge management with SM9.40 .

I am planning to use the below  libraries.

1. Knowledge

2. Interaction

3. Incident

Rest of the libraries , I want to keep it offline and do not want KM to touch these records.

How do I keep only the above libraries online and others offline ?

Just keeping the refresh interval to 0, is enough or do I need to false out the Table query also ?

AM seeing the below errors in the sm.log
