Default [Q] Unroot without flashing .tot again

Hi, I wanted to go back to pure stock but when I reflashed it disabled the d2w feature so in order to get that back I had to root it but I don't want root and I'm afraid if I try flashing again then its going to do the same thing. It's there a way to get rid of root without flashing a .kdz or a .tot
