There are no plans today for this. In general, we rarely recommend directly lifting and shifting on-prem policy to the cloud or Intune. I appreciate that some orgs have created a large set of complex firewall rules that will be labor intensive to manually recreate in Intune, but part of moving to the cloud and Intune is rationalizing and simplifying your device configuration to reduce overhead and costs as well as troubleshooting complexity (among other things). I also appreciate that this is easy for me to say but not as easy for you to do, but that is the current status.
