What "CPU Driver Update"? Are you talking about the Intel HD Graphics driver package? It is also for 6th gen processors; it is not limited to 7th gen and newer.
Your response was lost in the forum changeover. It was:
No, the name of the update is "Intel® Rapid Storage Technology (Intel® RST) user interface and driver for Intel® 7th generation and latest platform".
Ah. That's a chipset (PCH) device/feature, not CPU. Regardless, I believe that it can still be used with your system. Is the update failing?
