How to mark a Sybase ASE DB as offline for startup

I need to load a database dump into a target database, on Sybase ASE 16. In order to do that, the target database must be offline. Sybase ASE doesn't have a command to put a database offline, so my only possibility is to stop the DB server and restart it, taking care that the target database is not brought online during startup. This is my question: which command/option do I need to set so that a specific database is not brought online at server startup? I couldn't find it in the official documentation :-(
