Can I turn a Win8 installation for UEFI into CSM-Mode Win8

On my computer there is a pre-installed Windows 8 which works fine for
UEFI boot (Secure boot not necessary).

Now when I switch in UEFI setup at boot time the UEFI mode into the CSM (BIOS) mode
and restart then Windows 8 is not starting any more.

As far as I find out an UEFI-based Windows 8 can only boot with UEFI mode enabled.

So my question is: Can I turn an existing UEFI based Windows 8 installation into
an CSM/BIOS based installation (=a Win8 which boots successfully even when I enable CSM in UEFI setup) ?

If yes: How do I do that?
