I'm trying to set up my 2017 MBP with two external monitors. I have a Totu USB C Hub, TOTU 12-in-1 Type C Hub with dual HDMI inputs. It's supposed to allow me to use two external monitors with my MBP in clamshell mode but after exhausting SO and YouTube, I've found no good workaround. My machine only has two USB-C inputs (Thunderbolt 3). Anyone out here doing this?
The other posts similar to this were quite old and I'm looking for a solution specifically for newer MBP's with the two USB-C ports. Thanks,

Your problem is that you have chosen a USB-C hub - this means that MST is a requirement for supporting dual displays in a non-mirrored configuration. MST is not supported on macOS, but will work if you run Windows.
In order to get dual displays working, you'll need to either: (a) connect each monitor seperately to the two Thunderbolt ports on the Mac - directly or through your hub, or (b) get a Thunderbolt 3 hub/dock with dual display capability.
Such a Thunderbolt 3 dock could be for example the OWC Thunderbolt 3 Dock. With that dock you would need to connect your two monitors to the dock like this:
Monitor A: Connected to mini-DisplayPort port Monitor B: Connected to daisy-chain Thunderbolt 3 port
Note that you'll need cables that match the inputs your monitors support. That could be for example a mini-DisplayPort to DisplayPort and a Thunderbolt 3/USB-C to HDMI cable.
The OWC dock is just one option - many other docks are available from various vendors at various price points.
