How to simulate Docker container losing internet connectivity?

I'm using Docker Desktop for Windows, running a couple of linux containers using docker-compose.

These containers communicate with each other inside their own Docker network. One of the containers is set to push some data to the cloud.

I need some easy way to test the behavior of the cluster losing internet connectivity.

I do not want to disconnect my whole computer, just the Docker containers (without stopping them).

I tried restricting access of docker-compose in Windows Firewall, but that didn't work.

How can I achieve this?

Is there any Linux command I can run inside the running container to go offline?

EDIT

@vaibhand's answer disconnect a single container from the cluster network. Making it unreachable by other containers in the cluster. I need to disconnect the cluster from internet (simulating a real world internet connection outage), while keeping the internal cluster network alive so that they can still take to each other.

Use docker network ls to list available networks and then docker network disconnect <NETWORK> <CONTAINER>
