Installing Dapr on a Kubernetes cluster without Internet access

We are trying to install Dapr on a Kubernetes cluster in a private network. The environment does not have public Internet access (or ACR access). I'm wondering are there any ways we could install Darp offline without access to the public Internet. Thanks.
(In https://github.com/RicardoNiepel/dapr-docs/blob/master/getting-started/environment-setup.md#installing-dapr-on-a-kubernetes-cluster, either Dapr CLI or Helm requires Internet access)
