How do you turn off Do Not Disturb While Driving on 6S Plus?

How do you turn off Do Not Disturb While Driving on 6S Plus? Search show you select manual but there is no Manual option under settings, Do Not Disturb. Only selections that are available are Do Not Disturb, (on/off button), Scheduled (on/off button) Silence (Always or While iphone is locked) Allow Calls From, Repeated Calls (on/off button) Activate (for Bluetooth) and Auto Reply To and Auto Reply Message. Getting older and do not want to keep paying for services that come with control issues. Maybe downgrading to cheap phones with Cricket or something.
