simple answer: no
Here are some other options:
A) You could potentially remove the bios chip and have someone flash it for you, or order a bios chip preflashed(asus, badflash.com, etc. $20 or $30).
B) There is the possibility that it'll boot with the cpu and work even tho it's not "officially" supported, it'll just report the cpu name wrong on boot or something(which would be the easiest outcome, and is likely). This will allow you to update the bios.
C)Another option is to just take the board down to the local shop and have them update the bios for you (maybe $30 depending).
Hope for B then look at C and A
