Clevo are known to be the OEM behind many (all?) of System76's laptops. In Australia they're sold under the brand of Metabox.

The System76 Pangolin tech specs[1] match the Metabox Edge specs[2] and visually match as far as I can tell identically, and neither mention USB-PD or Charging capability. Metabox specifically call out USB-PD capability on their other range of laptops, so I don't think it's an omission.
