Shelly1 - CoIoT support Missing?

Hi everyone, had a problem with my HomeAssistant + Shelly1 integration where the router died and dhcp leases changed on the devices.

Apparently if I redo the configuration with CoIoT with the devices it will resolve the problem in future if it happens, so I wanted to test that.

Reading online, apparently any shelly device with firmware v1.10.x or newer has CoIoT support that has to be enabled in 'Internet & Security' settings.

Shelly1 = does not have that setting/option on it. Does Shelly1 not support it?

I can't find any documentation that states otherwise.

I have over 70 shelly1's and they're on firmware - 20211109-124958/v1.11.7-g682a0db

Thanks in advance everyone.

The below image is all I see where the settings should be..
