Hi,
Dev tools contain only console in OSS Kibana and also has profiler and grokdebugger if you have x-pack.
console.enabled: false should definitely work for disabling console. But profiler and grok debugger will need to be disabled separately as well. Can you please check if your Kibana has x-pack installed?
Also whenever you change /add/delete anything in Kibana.yml - when you restart, Kibana will need to optimize again. It looks like this in logs: log [15:03:08.119] [info][optimize] Optimizing and caching bundles for kibana, stateSessionStorageRedirect, timelion and status_page. This may take a few minutes
Can you please check if you see this in your logs?
Thanks
Bhavya
