You are confusing two different things. What you or ASUS is calling the Intel Chipset Driver, is really called the Intel Chipset Device Software, and the version you listed, V22.214.171.1241, is fine.
In general, the driver you saw in the thread you posted is for the Intel SATA controller on your board, which is part of the Z77 chipset. That is the Intel IRST driver, that is used for both AHCI and RAID mode usage. Intel left a very old, dead link for that driver in that information, must be a mistake. The latest IRST driver for your board is here:
I'm also sure that ASUS has an earlier version of the IRST driver on your boards download page, you can use either one.
These two drivers are not the same, and do different things. You should not, and really cannot, install the Chipset Device Software, and can install the IRST driver anytime, as long as your SATA mode is set to AHCI or RAID.
