Is there a way to change the default dnsPolicy without modifying every PodSpec?

I am looking for a way to use dnsPolicy = "Default" in kubernetes clusters I manage.

The docs mention that

DNS policies can be set on a per-pod basis. [...] These policies are specified in the dnsPolicy field of a Pod Spec.

Changing every PodSpec is a very costly operation for me. Is there another way to change the default dnsPolicy parameter globally for the cluster ?

Maybe via kubelet ?
