Thanks Rob for the answer.
I don't know if I'm looking in the right place but here:
https://github.com/apache/qpid-broker-j/blob/c018e1ac9d21e9f5eb38d2ae7a26a31e63c07fdf/broker-plugins/jdbc-store/src/main/java/org/apache/qpid/server/store/jdbc/JDBCSystemConfig.java
the default preference store is "Provided"...
Do you have a sample where the preferenceStoreAttributes is set?
I tried in the command line with -prop
"systemConfig.preferenceStoreAttributes={\"type\":\"Noop\"}
and in the initial config.json of the broker without any success...

It is where per-user preferences for the web console are stored. The default
is to use JSON - so at some point the configuration must have been edited to
use "provided" instead.
If not how can I configure my broker to use the NOOP one?

The type of preference store to use is defined in the attribute
"preferenceStoreAttributes" in the system config. The default value is the
JSON object "{\"type\": \"JSON\", \"attributes\":{\"path\":
\"${json:qpid.work_dir}${json:file.separator}preferences.json\"}}". If you
wanted to change that to the NoOp provider you could use "{\"type\":
\"Noop\", \"attributes\":{}}" I would think.

It's just never been implemented - I'm not sure why, I guess because there
wasn't really seen to be a demand.
