How to set mtls?

Initially mtls can be set via and but with 1.7.4 this does not seem to work. I am not able to find the right documentation where it would help me understand on how I can set it.

Have you tried following this link - Istio / Mutual TLS Migration ?

Yes, but what is confusing how are and mapped? Should we just set the mode for mtls? If so, how were modes defined earlier?

We have removed the config part from installation. Currently we support via peerAuth policies and is always enabled with sidecar injection.
