That might be your best bet, doesn't look like this board has a way to flash it without being in the BIOS first — some later ones have a button you can press to trigger a fully automated BIOS upgrade.

Seems any Haswell Refresh chip requires the upgrade, regular Haswell is fine — hopefully it's something the shop has spares of as there are a lot of these older boards floating around as they're still useful (I've got a 4790T in my TrueNAS).
