Blade 15 2018 Advanced with 2x 4K Monitors

Hi all,

I'm having a hard time finding information on how to best connect two monitors to my Blade 15 Advanced (2018 model). I want to get two 27" 4K monitors and daisy-chain them directly to the GeForce GTX 1070 (Max-Q) in the laptop (i.e., without a hub or eGPU).

The first and most basic question I can't seem to find an answer to is: does the GTX 1070 support MST (Multi-Stream Transport)? It has a USB-C/Thunderbolt port with DisplayPort, but the version isn't stated anywhere that I can see, nor is there any info about MST. The MiniDP port is version 1.4, but again it doesn't say whether it supports MST or not.

Then I found this page:
https://mysupport.razer.com/app/answers/detail/a_id/4144/~/refresh-rate-and-resolution-monitor-specifications-when-connecting-a
...where Razer lists three ways to connect from the USB-C/Thunderbolt port on the device, but

a) there's no device information whatsoever (does this apply to the Blade 15 2018 Advanced?),
b) it conflicts with some other info I read elsewhere (that the USB-C port on my Blade model is connected to the Intel GPU, but not to the nVidia GPU), and
c) there's no information on the other ports (MiniDP and HDMI) and what they support or don't support.

Bottom line, after spending the better part of a day on this task, I'm hoping someone here may be able to shed some light on this seemingly impossible ask!

Thanks!
