Portenta C33 and MicroPython LAN?

Official Hardware Portenta Family Portenta C33
1

I am having difficulties getting MicroPython to configure the ethernet port/controller on a Portenta C33. Looking into 'help(netwrok)' there is no LAN class listed:

object <module 'network'> is of type module
  __name__ -- network
  country -- <function>
  hostname -- <function>
  ipconfig -- <function>
  route -- <function>
  WLAN -- <class 'ESPHOSTED'>
  STA_IF -- 0
  AP_IF -- 1

I did find information on github indicating that I may need to use lwip. I do have lwip installed, but this seems to be configured for using the wifi module, instead of the ethernet.

Any direction to howto/tutorials/other documentation would be appreciated.
