Can you not delete the individual VM from the VMSS view on the Portal?
Action required from @Azure/aks-pm
@seguler you can, but you're not supposed to touch the vmss directly so I'm not sure if you run into out-of-support scenarios if something goes wrong.

My impression here (prehaps wrong) is that you can kubecrtl delete nodes and after some time perioud cloud prover will actually remove the machine @feiskyer can probably say if this is true or not. If it does the next call to az aks [nodepool] show should show reduced count since vmss is the source of truth.
@paulgmiller that is half correct. Yes you can remove a node using kubectl, no this does not change the node count. The aks scale settings are the source of truth so if for some reason a node is missing it will be recreated. As it should be.

Any update on this issue? This would be a really useful feature added to AKS.

Support selection of nodes to remove when scaling down.
At the moment when you scale down, the oldest nodes will always stay and the newer nodes will be removed. Would be a nice feature to be able to remove a selected node when scaling down or maybe manually.
This will enable customers to remove an unhealthy node which is otherwise impacting the entire cluster.

What happened: It often happens that a specific node within a cluster is unhealthy (for various reasons) but there is no way to get rid of that specific node.
What you expected to happen: Have the ability to remove selected nodes within the AKS cluster
