When the IoT network is turned Off in the Deco app, there is still an IoT network appearing. The Deco app won't let me screenshot, but I can confirm that it is set to off. The following screenshots are from the browser status page.

You can see that it is sending out an IoT network. Other networks, such as MLO that I have turned off, show correctly as off.

If I toggle the IoT setting on/off, I can actually see the network in my wifi list (on my phone, for example), and can even attempt to connect, but it never successfully establishes a connection. The network name dissapears if I reboot the units, however the web details never show off, even after rebooting.
