Hi @JonathanSiemering, thanks for raising this. I have checked the Azure AKS service, and these configs are currently not supported. Found this: https://github.com/Azure/AKS/issues/3879 which looks relevant.

Hi @hqhqhqhqhqhqhqhqhqhqhq, that i have missed. Luckily it's planned for development on the aks side already. Can the issue stay open for the period of time or should i reopen it?

I would recommend closing it for now and reopen it in future, thanks!

Wait for AKS feature to be implemented.
