Fortigate FW Rules

Hi Experts,
I recently started gaining knowledge in the field of networking and I hope you can help me further.

I’m using a fortigate fw. and is therefore the first entrance to my network, I would like to use the adblock rule (policy) within my environment that can be set instead of the free adblockers from edge.
Within my environment I use 2 types of server levels one of these is the production environment, which contains all the servers that are in production, and a test environment, in which I have installed all the test servers.

I was wondering if it is possible to test the adblock rule (policy) first in the test environment and then in production?

Thanks
