I want to block all incoming calls to a specific extension number

Hello,
I am using 3cx digital switchboard software. My version is v18.
I want to block all incoming calls to a specific internal extension. How do I do this?

Go to call forwarding on that extension and set an exception to end all calls.

I understand and thanks but is there any other method for this?
may be outbound rules can do this ???

Outbound rules are for.. outbound calls.
