Add Radius to AD Connector with Terraform?

I have an AD Connector configured in AWS and plan to use it with Workspaces. I’d like to add a second factor by configuring it with a Radius server for authentication. However, I can’t find it documented on how to add Radius as a second factor using Terraform. Any suggestions?

Looks like it’s in the works even though it’s marked close? Add Radius support for aws_directory_service_directory · Issue #12639 · hashicorp/terraform-provider-aws · GitHub
