Encrypted tls certificate support in k6

Hello,

I am new to k6, and trying to create load test, which would use encrypted tls (pkcs12 or pkcs8)certificate. Currently I am receiving different error messages and after reading through this topic Support for encrypted PKCS8 or PKCS12 private keys · Issue #2834 · grafana/k6 · GitHub
I understand that only unencrypted tls is supported. Can someone tell me if the situation is still the same?
