The only way that 2 Factor can be turned off if it was set up less than 14 days ago. If this was the case, you received an email with a link to be able to turn 2 Factor off.
If this was a new iPhone, it may not be possible at all to turn off 2 Factor.
Reading and understanding this Apple Support document may save you a trip to the Apple Store. The important text is:
If you're already using two-factor authentication with your Apple ID, you can't turn it off. If you updated to two-factor authentication inadvertently, you can turn it off within two weeks of enrollment. If you do, your account is less secure and you can't use features that require a higher level of security.

With no passcode on your phone, anyone who picks up your phone will be able to lock you out of your own phone in less than 30 seconds. Your decision on that one.
