dell t7500 uefi mod

[Madxxx2003]

hi i have a dell t7500 that i wish to convert to uefi i found 2 things 
1- the dell og bios is specialized phoenix bios that most likely cant be edited (the file is linked bellow)
2-there is a rare intel server board with similar enough specs (only differences is the raid controller and lan adapter) the intel s5520sc
can the intel board uefi capsule be flashed on the t7500 and if it cant can it be modified enough for it to work
