Is it possible to change the default auto scaling group created by eks_node_group?

We already know that with the eks_node_group resource block we get a launch template and auto scaling group already configured and attached to the cluster, by default. In this use case I am wanting add certain configuration line namely: termination_policies=["NewestInstance"] in the auto scaling group. But since I am using the default auto scaling group I am unable to add this particular line. How can I set my own config for the default auto scaling group?

The auto scaling group that this block creates (eks-abc-eks-node-prod-86c20f35-cb41-782a-e0b1-33356faea7a6) and it uses the launch template named (eks-86c20f35-cb41-782a-e0b1-33356faea7a6) also made default.
