No, you can't connect two screens in series via USB-C on this model, as it doesn't support daisy chaining. Each USB-C display must be connected directly to a USB-C port on the computer. As your PC only has one USB-C port, you'll need to use a USB-C docking station, which allows several displays to be connected at the same time via other video outputs (HDMI, DisplayPort, etc.). Nor does the monitor have a USB-C output for connecting a second screen in series.
