Don't mess with worrying about the BIOS version in the ON position until you get the BIOS corrected in the OFF position.
If you mess with the only currently working BIOS and something goes wrong, you will be in a tougher position.
The basic steps to fix your issue:
Boot up with the working BIOS in the ON (secondary/slave) position. Once booted, flip the switch to the non-working BIOS in the OFF (primary) position. Even though the non-working BIOS is selected, the computer will still continue to work correctly until it is powered off. Download the correct BIOS for the primary position from somewhere (?) and flash it to the card. Since the primary BIOS is currently selected, it will flash the primary BIOS and leave the working BIOS unaffected. You could get the correct BIOS from EVGA directly, or your could play roulette with the BIOS dumps available from techpowerup.com. As long as you don't mess with the working (secondary/slave) BIOS, the risks are low for attempting different BIOSes for the non-working (primary) switch position.
Power off and power on the computer. Does the BIOS in the primary position work now? If not, you may have downloaded an incompatible BIOS. Repeat as necessary.
Once you get the card working properly with the BIOS in the primary position, THEN you can worry about whether you have the best BIOS for the other (secondary/slave) switch position.
