I only access banks electronically if they accommodate Tor.
So they know when you logged in and what you did when you got there. So you can’t escape it there.
The bank only gets to know my physical location when I do a transaction where that’s unavoidable.
So you can’t escape this either.
Even if I were to carry a mobile phone on standby wherever I go, the bank would get nothing from it if I don’t run their app.
They would get nothing except the time, location, amount, business, and how that relates to the other purchases you make and all the data those transactions generate as well. That data is shared with the bank, Visa or MasterCard, and all credit reporting agencies. This is unavoidable too.
You are not getting out of this unless you allow it to seriously affect your life.
