Hi @ewbankkit. I can try to implement it. 😃

Current workaround:

resource "null_resource" "custom_endpoint" {
  provisioner "local-exec" {
    command = <<-EOF
      # Some settings here are duplicated from the ones set natively, so that we don't overwrite them.
      aws es update-elasticsearch-domain-config \
        --domain-name "${aws_elasticsearch_domain.main.domain_name}" \
        --domain-endpoint-options '{
          "EnforceHTTPS": ${aws_elasticsearch_domain.main.domain_endpoint_options.0.enforce_https},
          "TLSSecurityPolicy": "${aws_elasticsearch_domain.main.domain_endpoint_options.0.tls_security_policy}",
          "CustomEndpointEnabled": true,
          "CustomEndpoint": "${local.hostname}",
          "CustomEndpointCertificateArn": "${aws_acm_certificate.custom_endpoint.arn}"
        }'
    EOF
  }
}
