This is an optional feature that can be used to speed up the wallet setup process and reduce the chance of an NFC connection timeout occurring between your phone and card. If you toggle this option ON, you will see fewer assets already enabled when the wallet restoration process completes. If you toggle this option OFF, you will see a greater number of assets already enabled once you restore your wallet.
Regardless of whether you toggle this option on or off during the wallet restoration process, you can always enable any asset you need to later in your wallet.
