Hi AndrewDodd3,
Thank you for reaching out Microsoft Community.
Based on the device tech specifications from this link >> https://www.microsoft.com/en-us/surface/devices/surface-book-3/tech-specs, the Surface Book 3 has 2x Surface Connect ports (one on base, one on tablet). Therefore, you can use this a tablet with the Surface connect while extending its display using a Surface Dock 2. You can utilize the USB-C ports of the Surface dock 2 to get your Surface device display extended to external monitors.
If this answers your question, feel free to mark this post as an answer. Otherwise, don't hesitate to respond to this thread if there's anything else that needs to be addressed.
Kind Regards,
