LG X Venture ROOT NEEDED!!! LG-H700

[Android Central Question]

Hello, I've recently bought the LG X Venture from AT&T and would like to get some insight on the root process if there even is one. Keep in mind KingRoot doesn't work
nor does KingoRoot. My device is currently on the security patch April, 1st 2018
Build#: NRD90U Kernel: 3.18.31

Please help this phone is incredibly boring and I would like to add more customization.
