LM5021: PMP20809 module design question

Part Number:LM5021

Hi Sir,

       The AC to DC module of PMP20809 is suitable for my customer design except the Vout, is it possible that just change the feedback resistor to let Vout down to between 14V and 22V (original Vout is 24V). it will let our customer test it in PMP20809 and follow this board schematic and layout to accelerate the project.
