I'm not sure I understand how the CSM option is stopping you from the faster start/boot that true UEFI booting provides. What do you have CSM set to, enabled or disabled?
Yes, it is normal for the CSM option to not appear when Fast boot is set to Fast or Ultra Fast.
The CSM, or Compatibility Support Module, is used so a UEFI type BIOS can be used or run as a standard BIOS does. When CSM is enabled, a PC is not UEFI booting, it is BIOS booting. In order to UEFI boot with Windows 8, CSM must be disabled. That is why when Fast boot is set to Ultra Fast, the CSM option is removed, since Ultra Fast boot will not work if CSM is enabled.
If you have CSM enabled when using Windows 8, you are not UEFI booting.
