Office 2016 Customizing Setup

You can customize the install by running the setup with the admin flag.

Setup.exe /admin

A customization wizard will open where you can modify your settings.

Adding a setup property of SETUP_REBOOT = Never will prevent reboots during install

I copy the msp file to the root directory of the install media

Setup command is setup.exe /adminfile nameoffile.msp
