If you can, I do strongly recommend setting an instance name expression in the form definition. You can even do something like string("Favorite color form") if you really want a fixed string. A related concept is to use part of the system instance ID to make it more user-friendly: concat("Fav color: ", substr(${instanceID}, 6, 10)).
If that really doesn't make sense for your context, you could consider using a configuration QR code with the setting to hide form naming. This will only make sense if you share an App User between several devices. You can add to a configuration QR code in the same way we discussed in this thread. If you want to create the code programmatically, the setting you need is save_as in the admin section documented here.
