You might be able to get this to work, but not in the way you are currently thinking (and it would be kind of janky). The Tablet needs a USB-C port with Displayport alt mode, so a USB-C port that can also transmit Displayport signals. Not every USB-C port and no USB-A port can do that.
But Displayport supports daisy chaining multiple monitors from one port on the device. With multiple (pretty expensive) adapters you might be able to do it.
You would need a Displayport daisy chain adapter (a few Monitors have this built in) to get two usable ports from the single one on the dock and one that converts a Displayport and a USB-A port to USB-C with Displayport alt mode.
But this might still not work because of compatibility problems, so I would only try this, if you have free returns.
