Well, the good news is that you can turn off WiFi on the Smart Hub 2

Here's my screenshot. From the router settings. Going to the Advanced settings--->Advanced wireless>There's this button Off for 2.4GHz and 5GHz or you can press the Disable all wireless and switch it to a Yes.
"All wireless functionality on your Hub has been completely disabled.
To re-enable wireless on your Hub, set the 'Disable all wireless' switch to 'No'."
Yeah, it's true it doesn't have the LED light indicators like with other routers. It only has that circular blue light around the BT logo indicating internet connectivity. But sure, there is no blinking lights to indicate data transfer.
I agree, the automatic firmware upgrades are the biggest grip I have with the Smart Hub 2 router. Recently it has been happening a little more frequently once every 2 months. There was one in September and November the 6th. Usually they are meant to happen once every 6 months.
With TalkTalk I remember it was once in 6-9 months. But overall TalkTalk was a less reliable service than BT. Firmware upgrades also happen only in the mornings between 2-4am.
I'm looking to soon switch to Community Fibre FTTP where their Linksys router can be re-flashed with official firmware so that way I can disable automatic firmware upgrade.
I don't really care about the landline telephone service, I very rarely use it as I have RWG Mobile SIM that is very cheap. £20 year upfront which works out as £1.60 a month and you get 250 minutes, texts and 2GB data.
Alternatively, I've got another option for you. TalkTalk broadband (no line) – six months free for Universal Credit.

FREE average 38Mb speed broadband only (no line) for six months and you can then switch to a cheap SIM like RWG for phone calls.
Unfortunately, for now if you want landline phone with Digital Voice there isn't an option to use your own router and connect phone with it. That's the biggest restriction with Digital Voice. Only the ISP router has a telephone port and the Alexa phone handset is not compatible with third party routers.
But given that for £20 I can get Community Fibre 500Mbps or £25 for 1Gbps without landline that for me is a much better overall option.
The £20 social tariffs for 40/80Mbps aren't worthy especially if you've got FTTP as an option. But if you don't have FTTP all I can suggest is cheaper mobile tariff.
Or you can just keep the Smart Hub 2 handy for phone calls and use it separately. I know it can be a hassle. It depends on how much importance you give to the phone service. I'd like to believe that having a mobile SIM service is the better option since with Digital Voice you are 100% dependent on a reliable internet connection and if the power goes down then telephone service will also go down.
