Can I use remote_read (rest api sending data in snappy format) with Grafana Enterprise Metrics v1.3.0

I was using Prometheus and had configured my rest api as remote_read.
Now I am using Grafana Enterprise Metrics (GEM v1.3.0) and unable to configure remote_read with this as I had for Prometheus.
Can someone suggest how to configure a remote read to get data in Cortex from my rest api
