There is but its not 'officially' supported nor guaranteed.  You have to get the controller using the AHCI driver first, then shut down and put the firmware (BIOS) into AHCI mode.

Crap, I started to describe how to do this but then I noticed this board has three damned RAID controllers from three different vendors.  WTF?  Oh well, you can give it a try, but I don't know how this might impact the other controllers.

If using the integrated Intel ports via ICH7R, download the Intel AHCI/RAID Drivers (latest) here:

http://s89934018.onlinehome.us/DRIVER/iata78enu.zip

Extract/unzip to some temp directory.  Open Device Manager and Expand the Storage Controller category.  Right-click once on Intel 82801xx Controller and select Update Driver.  Select 'Not this time' to Windows Update > Next > 'Install from list or specific location' > Next > 'Don't search, I will chose the driver' > Next > Have Disk.

Point the Wizard to the temp directory containing \iata78enu\Driver\iaahci.inf and click OK.  Select "Intel 82801GR/GH SATA AHCI Controller" (ICH7R) and click Next or OK to install.

If you don't see "82801GR/GH" (ICH7R) or it reports no compatible hardware found, you may need to uncheck 'Show compatible hardware' and try again.

Restart and change the Intel SATA controller to AHCI mode in BIOS.  Save and Exit.

Again, this is not guaranteed to work so plan accordingly.
