Hardware sync + K8s generates lot of network interfaces and disks

I use MAAS to manage physical machines part of a Kubernetes cluster. Once deployed the machines (nodes) are then added to the cluster via kubespray. It works.

Now, I find the MAAS hardware sync feature very useful, nevertheless when Kubernetes generates network devices for pods, these network devices are added/synced to the MAAS in form of new empty “fabrics”.
Moreover, longhorn, the solution we use for storage on the nodes generates new block devices. These are no physical disks, but MAAS reports them too.

Is there a way, or what is the best way to configure the hardware sync to ignore k8s network interfaces (or longhorn non-real disks) ?
Thank you!
