Setup Azure App gateway point to private IP of internal load balancer of Azure container app env without using private dns zone is not possible.

The direct answer I can say for this "NO". I understand that you are trying to setup a private Azure Container App behind an Application Gateway so that it is only accessible via the Application gateway and not accessible directly

Because without a private DNS zone or your own DNS server, the Application Gateway will not be able to resolve the internal FQDN of the Azure Container App to its IP address.

In general, this required for effective routing of traffic. For any internal container apps environment a priavte DNS zone or its own DNS server is mandatory which resolve the container apps domian name to stattic IP.

So its always mandatory to use a private DNS zone as per the recommondation.
