Short answer: Installing NSP files (game, updates, or DLC) on a Switch requires custom firmware (CFW) and a set of tools; it’s not supported by Nintendo, may void warranty, and can lead to account bans if used on an online/stock console. Below is a technical, step-by-step overview of how the process typically works for NSP updates/DLC and specific considerations for My Hero One's Justice 2. This is informational only — do not follow on a stock/online console.
Nintendo actively monitors for NSP installations. If you go online with a legit eShop copy, they won’t ban you. But if you install My Hero One’s Justice 2 Switch NSP with non-official tickets, your console will eventually be flagged.
Protective measures:
Recommended: Create an emummc (emulated NAND) for all NSP installs. Keep your sysNAND clean and legit. Never install NSPs on sysNAND if you play legitimate games online.
