unattended-processing

I'm creating an auto-updater that can run MSIs and EXEs. These MSIs/EXEs aren't my own. I'd like to use any unattended/silent install option if it exists. Is there some way to determine if an MSI/EXE has some sort of unattended install support and, if so, get the right argument so I can pass it to the file when I run it? I know, by default '/quiet' is the silent install option, but I'm also curious about EXEs and any MSIs that maybe have customized this option. This question - detect msi parameters for unattended install - is similar, but the links in the answer are broken and I can't figure
