Turn off Internet access for a host

[Raymond]

We have a Rutx11 installed on our boat and are using Starlink for Internet access.

When we are crossing oceans, data can get expensive due to a couple servers that run (large backups, etc). We still need those servers to running for local use.

Is there a way in the router to shut off Internet access for a client but still allow local access?

If it matters, Starlink is connected through Ethernet to the Rutx11.
