BQ24780S Power supply laptop controller firmware?

Hello everybody!
I have a laptop with Nuvoton npce285pa0dx and BQ24780S power controller. I want to understand how these controllers work and do they have their own firmware or is it stored it the BIOS. I also want to edit the BQ24780S’s firmware so it would allow my laptop to take more current from my 100w usb type c power adapter and not current throttle. ANY advice/source/information is welcome! Thank you in advance! :face_with_monocle:
