How to enale url enctryption on Grafana portal while diplaying dasbhboard

I want to enable url encryption on grafana in-house portal. When we design any sample payload with lets say influxDb/Mysql as database. On defined interval dashboard data will get refreshed by calling rest call to server in backend mode, while making call to server they have query parameter having sql query which designed for dashboard. Anyone on network payload easily can grab the sql details.

I want to make those rest call to secure or may be encrypted. Do we have any configuration on grafana.
