How do I make changes to Shortcut Cards?

At the bottom of the Shortcut Cards, tap Settings to go to the edit page to add, delete, and short cards. You can drag and drop any shortcut card to adjust the order by long-pressing it (dragging and dropping to adjust the order is not supported in Button Mode).

Open the Zepp app and go to Device > Amazfit Active 2 NFC(Round) > Shortcut Cards to add, delete, and sort cards.
