LMG2100EVM-078: LMG2100EVM-078 as boost converter?

Tool/software:

Hi TI, 
We have EVM board - LMG2100EVM-078.
It is working as buck converter with dual PWM signals with all the necessary changes made on the board for dual PWM.
It is also mentioned that we can use it as boost converter. Even after using the low input PWM, It is not working as boost converter. Please let me know how i can use this board as boost converter with all the necessary changes to be made on boards and how to program what PWM signals to be given from ESP32.
