Set $_HANDLER environment variable AWS Lambda in Dockerfile or via terraform

Question

I'm looking to add CMD override for an AWS Lambda via either terraform or docker. The lambda has type image since it is being run from a container. Trying to add the handler through terraform gives

Message_: "Please don't provide Handler or Runtime or Layer when the intended function PackageType is Image.",

Is there a way to set the _HANDLER to something and be used within the Dockerfile. CMD "${_HANDLER}"

Ie. $_HANDLER = $LAMBDA_HANDLER CMD ${_HANDLER} will then point to the lambda handler?

The image_config block allows you to override the command and entrypoint of the container. For example:

image_config {
  command = ["app.other_handler"]
}
