Hi,
I'm afraid there isn't a direct way to integrate lwip_dhcp_bm example from MCUXpresso SDK into Zephyr. You will need to port the example including application, drivers and stack. Nevertheless, this action would require significant effort.
If you need this functionality in Zephyr, you’ll likely have to implement it yourself using Zephyr's native networking APIs.
I'm sorry for the inconvenience.
Regards,
Daniel.
