Essentially no, but they can still help you if you're locked out of a device that you purchased. Whether you don't know the Apple ID associated with the device or it's disabled, Apple will walk you through the steps to reset the device. If you need a computer and don't have one, visit the nearest Apple location for more assistance (your cell phone carrier likely won't have the option, so get ready for a road trip if there isn't an Apple Store near you). Assuming you don't have your Apple ID, the password, or a way to get the 2FA, call Apple support for assistance. It can take several days to get this information updated, you may have to provide the card on file with Apple, and you may have to provide proof of purchase (sorry, Facebook's Marketplace and Craigslist messages won't help here).
