Looking for Apple EFI ROM for GTX 765m


1- have installed nvidia geforce gtx 765m sager laptop 2011 imac 27. works fine except no boot screen or brightness control (i haven't checked if lightning port supports external monitor).

2- have had lot of success flashing pc video cards work mac pros (ati hd 5770, ati hd 7950, nvidia gtx 680 mainly) geniuses on site , @ netkas.org. conversant general procedure of backing existing bios in windows or dos (using atiflash or nvflash), using terminal patch bios in osx , going windows or dos reflash card patched bios.

3- know apple used both nvidia geforce gtx 755m , nvidia geforce gtx 775m in late 2013 imac 27's.

so... has or can "frankenstein" efi bios 1 or both of 2 apple cards work on aforementioned card? me out and, have read, out @ least few other people. right injustice apple has inflicted on user community (especially 2011 imac 27's , melting ati video cards).
 

did ever reply or did find rom image?

aside ... gtx 765m working high sierra ?
