How does one add a NIC to node in node_pool and provision node, e.g. install DPDK?

Hi, I need a high-throughput data plane so I need to add an additional network interface to my nodes, and provision the nodes with DPDK libraries. The second topic - how to provision a node - seems like a very common use case but I have yet to see an example or discuss in the context of the azurerm provider. Thanks in advance
