At some point you have to let go of your thesis. At some point it’s as good as it’s going to get. You can’t anticipate every comment you could get from examiners. You can’t write things in an effort to prevent questions. It doesn’t work that way.
For any kind of creative work – and a thesis is a creative work – there comes a point where you have to stop, be happy with what you’ve done and move on. Moving on after submission means preparing for the viva, using the solid foundations of your research and thesis.
Let go when you submit. You’ve done as much as you could possibly do.
