Yes, you can share a Wireguard connection using WireSock. However, I need to know: how does your laptop connect to the Internet? And, are you using WireSock in NAT mode or with a virtual network interface?
For instance, if you’re using WireSock in NAT mode and your laptop connects via WiFi, you can simply share the WiFi connection to the LAN using Windows’ built-in Internet connection sharing feature. You can also use the Windows WiFi Hotspot; however, in this scenario, the Xbox would need to connect to the WiFi network shared by your laptop. More details will help me provide better guidance.
