The only installer options are described https://npp-user-manual.org/docs/command-prompt/#installer-options
Unfortunately, the NSIS installer technology (which is what Notepad++ uses) doesn’t give a lot of command-line-options. And the developers of Notepad++ want to focus their attention on the application itself, not in rewriting the installer software.
Since you seem to be an admin who is installing on multiple machines, I would suggest creating your own bundle: either start with the portable/zip edition, and customize the settings, then make your own zip (or self-extracting-zip exe) which you distribute; or start with the installed version, customize the settings, and zip up install-directory + %appdata%\notepad++ and bundle into a zip or self-extracting-zip for distribution.
