ST X-CUBE-CELLULAR, BG96 modem service how to restart?

[jiangpen]

I have a STM32H7 running ST X-CUBE-CELLULAR6.0 package on a BG96 modem.

It works fine, but some time I need restart the modem and service.

while current cellular_modem_start/cellular_modem_stop API are not enough to restart the whole service, for example reset modem and restart service to get IP address.

May I know if any way can gracefully restart the modem and cellular service?
