Rooting Asus Zenfone 4 Z01KD/ZE554KL 7.1.1 - Unlocked, TWRP installed, can't root?

Hey I just picked up this phone and decided I would like to maximize it to its fullest potential, and root it as I have done with previous phones. This ones giving me a hard time, and I just can't seem to find the proper info for it.
I have unlocked the bootloader, flashed TWRP 3.1.1 and want to gain root access. I have followed several guides, used every possible one-click unsuccessfully, and tried installing SuperSU with TWRP. After I reboot, SuperSU is installed. I'll open it up and it tells me the binaries are occupied. I've tried downgrading and updating the binaries but I get errors. (I believe this is because it must be rooted first - of course.)
So I'm stuck unable to get any further. If anyone has any suggestions, I would appreciate it. Is this phone with this configuration unrootable? There must be a way if I have recovery right?

Asus Zenfone 4 Z01KD/ZE554KL
Android Nougat 7.1.1 - 14.1060.1708.63 (NOT 1708.70)
TWRP 3.1.1 installed
