Upload your own certificate you want Cloudflare to use for edge-to-origin communication to override the shared certificate. Please note that it is important to keep only one certificate active. Also, make sure to enable zone-level authenticated origin pulls by making a PUT call to settings endpoint to see the uploaded certificate in use.
