then is it ok to use RMNET as use case?

You also can try this script to have DHCP on MBIM interface:

elementzonline/GSMModem/blob/master/SIM7600/mbim-set-ip/mbim-set-ip

#!/bin/bash
#
# mbim-set-ip script version 1.0
# Modified mbimcli IPv4 IPv6 parsing script based on parts of project https://github.com/grandcentrix/thinkpad-x260-modem-scripts

#
# Installation & Usage: 
#
# Verify that the cellular module is exposing the MBIM interface over the USB interface. 
# Use mbimcli to check status for the cellular connection and enter the PIN code if necessary. 
# Configure mbim-network.conf and place in /etc/ (example file included in the archive, check link bellow for details).
# https://www.freedesktop.org/software/libmbim/man/latest/mbim-network.1.html
# Start the mbim data connection with command:
# mbim-network <MBIM-INTERFACE> start
# Ensure execution of mbim-set-ip script with sufficient system priviledges
# ./mbim-set-ip <MBIM-INTERFACE> <NETWORK-INTERFACE>
