Can I recover data after it’s been erased on iPhone?

Only IF there is an available backup.

And FYI … “Automatic iCloud Backups” are the iOS “Default” setting.

See details here:

What data?

Do you have a backup?

Unless you have a backup of the data that was on the iPhone on another Mac, PC or on iCloud......you have no data to recover.
