UEFI Windows installation (DISM manual method) cannot copy boot files to internal drive.

I am trying to install Windows 10 on my late 2013 iMac with a FusionDrive. This install method allows me to create the different partitions which didn’t work through BootCamp. However the bcdboot command is never able to copy boot files to the internal drive. Maybe the FusionDrive is causing the problem? It is in great functioning condition and no bad sectors are reported. Maybe I have to disable SIP? I’m lost here. Thanks.
