How to make population growth rate of a province zero?

[Glisterr 62]

I am trying to make a realistic effect of the demilitarization of the Rhineland for my 1920 scenario, I made the population in the provinces extremely low so germany can only recruit like 10 troops there, but how do I prevent the population from growing, or make it grow at a VERY slow rate?

Is this possible?

Thank you in advance.

You can make a starting event to make it a wasteland and reverse it when the Rhineland is remilitarized.

Thank you so much for the suggestion

@Beter Griffini made an event that when germany declares war on france the 3 provinces on the maginot line become wasteland (so germany cant go through it, they would need to naval invade or invade belgium) and after france loses paris the maginot line goes to german occupation)
