WHAT IT DOES

What unassign_system_template does on FortiManager MCP Server

WHY IT NEEDS A POLICY

Why unassign_system_template needs a policy

Unassigning a system template modifies the configuration state of a managed firewall device by removing its template association. This could affect device behavior and network configuration, but the action is reversible (the template can be reassigned), placing it in Write rather than Destructive.

From the tool's definition 'Unassign a system template from a device' — removes an assignment/association between a system template and a device, which is a reversible configuration change (the template can be reassigned).
