CoreDNS on GKE 1.13

Cluster information:

Kubernetes version:
Cloud being used: GCP
Installation method: GKE 1.13.7-gke.24

we know that GKE v1.13.x uses kube-dns rather then the core-dns which is now the default on kubernetes v1.13.
we wanted to install manually the core-dns and replace the kube-dns deployment, but seems like in order to do so a feature gate should be enabled (CoreDNS=true) and this is not possible on GKE.

is there any workaround for this issue?
