DMZ kind of network design in the AKS

Question

I am looking for some guidance on a network design for AKS where all the node pool are in unroutable subnet in a vet and I want to use another vet subnet for the load balancer.

I tried searching it in the documentation and couldn't find any reference. Has anyone have any experience with it?

We cannot peer the networks as it will not have different set of non routable ips a bigger range for the nodes. I did this in aws but looking for a way to do this in aks.
