Elastic search 8.6 (SSL enabled) certificate check disablement

Recently we installed Elastic search 8.6 (SSL enabled) which is running as 3 node in cluster n kubernetes using the operator provided by Elastic. When we call ES from external client, after placing the Certificate (client generated) , getting unknown host Exception.
As we are running both client & ES in same kubernetes cluster and Host level check itself is not required.

So is there a way to get rid of this error

Or is there any way to disable SSL certificate check from Elastic search?

I assume you are interested in the SSL setting on the HTTP interface. Please refer to the documentation here.
