I’m in the same boat I’m just an IT Engineer/Manager I try to use off the shelf solutions for deployments our dev team is busy with non-client stuff. I build silent deployment packages but the .exe or base base .MSI has to already support it. Flexera Admin Studio is a great option but it’s very spendy.
I work for the local county—they don’t spend money on anything except 30-lifer’s salaries.
