When providing external customers with access to specific dashboards, we need to prevent them from using Global Search to navigate to other pages in the Zabbix frontend.

For example, searching for a host may allow the user to open a page displaying its internal IP address. Even though access is restricted through host group permissions, this information may still be visible on pages the user is allowed to access.

It would be useful to have a dedicated option in User roles to disable Global Search while keeping access to the dashboards and other permitted sections.

This would allow administrators to provide external users with a more restricted frontend experience without requiring custom modifications.
