How to block Psiphon VPN from accesing my WiFi Hotspot

Good day. I’m using a Windows-based captive portal (MyHotspot). Unfortunately, individuals using Psiphon are using my internet for free. How can I block the traffic of Psiphon using Glasswire.

Why not uninstall that unsecure VPN and harden your routers credentials? Update passwords for the login, 2.4/5GHz networks, etc.
