Remove or Deactivate Computrace from Dell Bios (Optiplex 745)

[Blaggah]

Hi, I'm not sure if this is the right section to the request but since it's related to hackintosh so i thought i'd post it  here.  I've bought a few Dell Optiplex machines in the hope that i'd be able to turn them into hackintosh but the 745 optiplex ones to be exact have computrace active under the bios.   I've tried everything I could by resetting the bios, clear cmos and no luck.  Now, i'm not exactly sure if by tweaking the latest bios will somehow remove the computrace or deactivate it.  If there's any hope, please help guys.  I'd hate to get rid of them because they make such great little hackintosh machines.  Thanks in advance.
