Welcome to MSFN.
You can start by reading this
crash course on application switches, which are the very first step in unattended installs for applications.
Next, you can use the search function on this forum to find the switches you are looking for if you don't know them.
When you master this, you can start by reading about Windows Installer properties and Orca for editing MSI setups.
Hope this gets you started.
Also, don't hesitate to ask, but try searching first.
