Windows Multipoint takes port 80

Question

In a Windows Server 2016 Standard, I had to install Multipont to add licenses

But Multipoint takes the port 80

With the following command

netsh http show servicestate

you can see

Server session ID: FF00000520000001

        Number of registered URLs: 1
        Registered URLs:
            HTTP://+:80/MULTIPOINT/IMULTIPOINTCERTIFICATEREQUEST/

How can I change the port number?
