Rooting android 7.1.1 December 2017 security update without bootloader unlock (kbin.social)

Hello, I am trying to temp-root my Motorola DROID MAXX 2, and I can not unlock the bootloader. I want to temp root so I can overwrite the bootloader with my own, unlockable version. Does anyone know of a temp root that would work? I have already tried dirtycow, RockMyMoto, and PwnMyMoto.

Unfortunately, I realized this isn't going to work. The bootloader stored on the eMMC is the second stage in the boot process. The first is a smaller bootloader stored on a ROM, that verifies the second stage, so patching the second stage would require desoldering the rom and reprogramming it. I would still like to find a temp-root, as there is a TrustZone exploit which could be upgraded for this version of android which could unlock the phone.
