Hello and welcome to Just Answer. You cannot drive the unit as you are already in a derate and will soon get the red stop engine light below are the faults you have. You cannot even perform a regen to help as it too is now disabled. You can only have a tow or call a Mobil technician out to fix on the spot.

Fault Code: 3714
PID(P): S115
SPN: 1569
FMI: 31

Engine Protection Torque Derate - Condition Exists. Critical fault codes related to engine operation are active.

Immediate engine power derate. This fault code is for information only, and indicates that an engine power derate has been implemented in order to make sure that the critical fault codes that are presently active in the ECM are addressed as quickly as possible.

Fault Code: 1883
PID(P): S324
SPN: 3251
FMI: 2/2

The aftertreatment diesel particulate filter differential pressure sensor is reading an erratic value.

Active aftertreatment diesel particulate filter regeneration will be disabled.

Possible causes of this fault code include:

Excessive engine oil or diesel fuel being introduced into the exhaust system from the engine

A damaged engine fuel injector causing unburned diesel fuel to enter the exhaust system

The aftertreatment system must be inspected after making the appropriate repair outlined in this fault code troubleshooting tree. Progressive damage to the aftertreatment system may have occurred. Remove the exhaust aftertreatment system from the vehicle to inspect it for potential damage and reuse
