It will not show there because it is a network protocol, not a device.
Go to Control Panel>Network Connections and right-click your NIC,
select Properties and in the General tab, you will see the installed services and protocols
and if they are bound to the NIC or not.
If NetBios is not there, click Install and then Protocol, then Add and select NWLink NetBios and Click Ok.
Now, it will show up where it is supposed to show up.
