Trying removing consent to receive text messages on that number, or that it's only a land line and only phone calls are accepted.

You might even try to block incoming SMS. In fact, you might also try a forward with Twilio or free Google voice number, since a lot of SMS TOTP refuse to with with those numbers :)

I've even had success removing my phone number entirely from certain types of accounts, but sometimes I had to deliberately break the account (eBay) and then it tries to get you to confirm on each login which you can sometimes bypass by changing the URL or clicking the company logo.

Be sure to have strong security in other ways; strong, non repeated passwords.

But this is truly insane. Large banks don't even offer the option of TOTP but instead require far more insecure SMS. Maybe they'll offer RSA dongles, because they never bothered to remember when they all got completely leaked ten years ago or how they accepted $10M to completely compromise their constants.

What can you say, large enterprises are behind the security eight ball, as always! It's a tale as old as time.
