I have lost my keystore for my published app and I didn't add Firebase to it. I contacted the support they said I need to publish a new app with a different package name.

So, I need a way to send a notification to all users to install the new app (without FCM of course).

How can I do this?

Simple answer:

You cannot :) If you had your keystore key, then you could setup FCM and use it for sending messages to your users, sadly you do not have it setup and without a key it will not be possible anymore.

Suggestion:

For this to not happen again, store your keystore into Google Play Console App Signing section, and this is how to do it.

Good luck :)
