Why don't you just check it on the official website? All the information you need and are asking for is there. I'm not saying this to be mean, it just seems logical and easier.
I would suggest flying somewhere for a few days (even just for a weekend) at the end of November, then coming back but you should have a return ticket. Then I think it should be okay.
But you do realize that having a Thai bank account could cost you quite a lot in transfer fees anyway? You can use tools like Wise to make such transfers (to minimize fees) too, but for what? Just to be able to pay by QR code? It's not that people aren't interested in having a bank account - they simply know it's not worth it. There's a reason why you can't have a bank account with a DTV visa, and that's completely fine.
Imagine walking around in 2025 not knowing there are many ways to solve this issue. As Marianne said, use tools like Revolut or Wise smartly. You can even buy premium accounts for higher withdrawal limits, and you may also get cashback. There's really no need to have a Thai bank account with a DTV visa.
