If you have a phone that tracks your full phone history, you might be able to delete individual instances of phone calls.
But for the redial function you may just have to call a random number to clear the redial.
But if you are afraid of your phone getting into the wrong hands (and you can’t set a lock on it), you should really just find another way to manage your bank accounts.
I’m glad you asked this question though, because it is a serious security risk that I had never thought of before.
I don’t believe there is a way to do this.

Get a bank that writes more secure software. It’s a function of their end, not yours.
