EKS DNS Issues, after enabling `service_ipv4_cidr`

Hello, recently we found that our cluster does not correctly resolving dns configuration of aws eks cluster. So after we implemented:

   kubernetes_network_config         {
       service_ipv4_cidr             = "10.100.0.0/16"
   }

Inside of all pods we get wrong nameserver

/ # cat /etc/resolv.conf 
nameserver 172.20.0.10
search default.svc.cluster.local svc.cluster.local cluster.local eu-central-1.compute.internal
options ndots:5 

At the end it should be 10.100.0.10 but not 172.20.0.10

Is there any idea why it is impacting?
