How to disable / block Microsoft Store in Windows 10 Pro by firewall?

I want to lock Microsoft Store on Windows 10 pro in a corporate environment. After reading relevant articles on this matter and testing them on my machine, I see that Windows 10 Pro does not support this feature (either through Group Policy (not recommended by my Administrator) or the Registry.

Now, I choose another solution, that is, block it with a firewall. If feasible, can anyone show me the rules on how to block Microsoft Store by firewall? I am using a tool to configure this rule.
