Adwords MCC script to see which campaigns are opted into "search network"

[M2018]

Hi!

I want to make sure that all my campaigns opt into the "search network". I am trying to write an MCC level script to find campaigns not opted in and to print it. 

I don't see an option here to find this specific setting. Is there any way to accomplish this using scripts?

Thank you!
