That's not how load balancing works. When you setup an Azure load balancer it will send traffic to any of your backends configured in the load balancer, unless they are unhealthy. So, if you configure this correctly then you do not need to do anything in event of of an unhealthy backend, it will be done for you.

You just need to make sure that the health probes you configured on the load balancer give an accurate view of the health of the service.
