How to be sure WiFi radio is disabled for OPi Zero

[Lucil]

In the context of this topic, after removing network-manager and configuring the network "the old way", via /etc/network/interfaces, what is the proper way to make sure that the WiFi radio is not emitting?

 

I plan to place my OPi Zero next to the router (wired connection) and I want to make sure there's no unneeded radio interference.

 

My /etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp

By commenting wifi drivers in /etc/modules ?
