How can I set maxIdleTimeMS by command line or mongo-shell? So, I have deployed my PHP application (using Laravel). However , I've noticed a high connection number in connection pool.

I would like to know how could I to set the maxIdleTimeMS parameter through MongoDB Shell or command line (or even via configuration file)?

Thanks in advance!

UPDATE  


  Please, see the important note on below comment from @jmikola
maxIdleTimeMS is applicable to MongoDB drivers and is managed on client side. It has nothing to do with MongoDB server so can't be set inside shell
