Disable "Add data" tab in kibana

I have user and associated roles with it.

these users are only allowed to read some index and create visulization and dashboard.

but on main screen it has "Add Data" which then shows what kind of logs and metric you can add to it.

how can I disable this so user won't even see this.

I am running 7.10.1

for example this

I would like to completely disable this

Unfortunately it's not currently supported. There's an open issue at https://github.com/elastic/kibana/issues/21911. Setting the default app in advanced settings to app/kibana_overview may mitigate how frequently the page is seen, but there's not a way to hide it yet.
