Filter unity ads depending on user age.

I recently finish my first game with ads, and happens that it target child’s. So I need to be worrying about user age for the ads.
The point is : I’m wondering if there is any way to filter the ads depending on the user age. I can’t find any setup for filter particular placement or change the filter type on code…
The only solution I can think is to have a different project for different ages, I don’t know if this is posible…

Thanks.

You can set age and category filters for your app in the dashboard:

This is at the project level though. There is no way to filter content for specific placements.
