You can inject it into CTRNAND to allow the console to boot without a SD card though there is not much reason you would normally want to do that, it might be useful in the unlikely scenario your SD card corrupts or fails while you're away from home and have no chance to fix it, but you have a bunch of retail games with you that you would like to play. Luma3DS Updater has an option to inject to CTRNAND built in.
