Is it posible to convert an ACARD ARS-2032 cd controller to ARS-2032D DVD controller?

I noticed hardware is same, could this be posible to simply upgrade ARS-2032 firmware with ARS-2032D one?

ARS-2032 and ARS-2032D look like same, but it different, you can use EEPROM writer write 2032D data to EEPROM IC and put both IC into 2032, it won’t work.
