[Question] Removing TWRP - Sony Xperia Z3

Hi friends,

So the situation is that I want to update my Sony Xperia Z3 from v5.0.2 to the latest version of Android, my phone is rooted via KingRoot, and I can't seem to get the latest update because everytime I do, TWRP always shows up when my phone is rebooting. I do not know how to remove TWRP, will I have to unroot my phone and then update to the latest version? Or is there a way to remove TWRP?

I appreciate you guys to help me out on this one :)

Thanks!

Device information:
Sony Xperia Z3 D6653 (Build number: 23.1.A.1.28)
