How to disable a specific cipher for TLS 1.3 on Azure AKS with ingress controller?

I have a Kubernetes cluster on Azure AKS with an ingress controller that uses TLS 1.3 protocol. I want to disable a specific cipher suite (e.g., TLS_AES_128_GCM_SHA256) for security reasons.

I've tried configuring the "ssl-ciphers" parameter in the ingress controller's configuration file, but it doesn't seem to work for TLS 1.3. I suspect that I may need to configure the cipher suite differently for TLS 1.3 than for older SSL/TLS protocols.

Can anyone provide guidance on how to properly disable a specific cipher suite for TLS 1.3 on AKS with ingress controller? Any help would be greatly appreciated. Thank you!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
