Nvidia G-sync on external monitors on new ALIENWARE M15 RYZEN EDITION R5 laptops using USB-C

I can't find information if this is supported ,  I know USB-C to DisplayPort  is 100% compatible and done this way on other brands laptops now question is if USB-C port is directly wired to the Nvidia GPU to have G-Sync on external monitors with ALIENWARE M15 RYZEN EDITION R5 laptop?.
