There’s no way to do that I’m afraid. You can see current rough data usage and you can turn on “Low Data Mode” to use less data, but otherwise no way of stopping your data usage at specific points.
Your best alternative is probably to see if your network provider has the ability to send you notifications/texts when you’re running out or have run out, I’m afraid.
