Azurerm_kubernetes_cluster and network security group

Hello everyone,

i’m trying to set up a kubernetes cluster using azurerm_kubernetes_cluster resource.
All works well. One of the hiccups i’m working on is the randomly named network security group created for the nodes pool.
I’ve found somewhere that, if there is already a NSG attached to the subnet where the pool will be created, then that NSG will be used. But this doesn’t seem to be the case. A security group with a random name is created anyway.

I know i could retrieve that name using data queries, but the question here is if there is a way to define a specific NSG to be used instead of creating a new one.

Thanks in advance,
a.
