TLS Client Certificate?

Hello,
.
We would like the TV to use a TLS client certificate when connecting to the Widevine licensing server. How can we best do this?

We don’t provide specific guides on this, but you can refer to TLS and Root Certificates. Thank you.

Thank you for your reponse.

The linked webpage relates to TLS root certificates for verifying the server certificate. However, we are looking for details as to using a TLS client certificate
