I have a 4g modem at home and I would like to get notified when it goes offline. No these 4g modems do not support static Ip so having something like uptime robot unfortunately is not possible. Is there another way to get this to have some form of outside ping monitoring without a static IP? I tried setting up ddns on 4g modem but didnt seem to work..

Can you connect something like a raspberry pi to the modem and send a request to some server?

You could build a heartbeat app. So you send a request to the heartbeat app and just save the timestamp of the last request.

If the heartbeat app doesn't get a request for some time, you can assume the modem or e.g. raspberry is down.
