iPhone 8 disabled & NEED TO RECOVER DATA

iPhone 8 is disabled, and has valuable data on it. I forgot my password so my phone got disabled indefinitely, and now I need to connect to iTunes in order for it to restore the phone. However, I don't have a backup for the data on the phone, and I don't want to lose anything in the restore process- what can I do in this case? I called our local apple reseller, but they can't help me without formatting the phone. HELP. Can the support team re-able the phone if I pass on the serial number?
