No, you don't root the chipset you root the firmware. And the firmware is applied different by different manufacturers. On this device, you can't access Vol up from fastboot fx to do a OEM bootloader unlock. Others, like Sony, encourage the Open Source community by having an official way to unlock the bootloader. Others do everything not to.
There is two ways of rooting, either to be able to unlock the bootloader so you can flash a custom recovery (like TWRP) or using an exploit inside the system itself to gain access to the system.
