ADP5090 Vref tolerance

The tolerance of Vref in ADP5090 is quite large 1.14 to 1.28V. So setting TERM with 1% resistors to not overcharging a Li-ion battery over 4.2V would result in unacceptable variation due to tolerances (3.89-4.47V).

Is it possible to use an external reference with tighter tolerance for setting the overcharging protection threshold?
