Automation of Administration Tasks

I am actually new to IRIS, and we are DevOps/PowerShell/Ansible team. We want to achieve certain administration tasks like updating Memory, Heap size, Lock size etc., in Management Portal through PowerShell. Is there any way i can achieve this without out logging in into Management portal. Off course, we have namespace, user id and password details. We have installed ODBC drive and able to update tables in the IRIS database. I have seen updating information in management portal getting updated in cpf file but vice versa i am not aware. i did not try though.
