No wonder, if you really have inserted the NVMe module into the CSMCORE module.

Hello,
I encountered the same problem.
I followed instructions from thread on ami-uefi bios nvme support (the MMTool route) and inserted the small version of module (option "Insert Compressed") in the same volume as CSMCORE is listed in. That was successfull.
However, saving the image generates a "Firmware write Error". I've tried inserting the module using the other option under "Insert FFS Options" and encountered the Error too.

I'm going the MMTool route, because using EUFITool generates extra pad file and I haven't found any fix to that.
I would post my bios file but I'm yet to figure out how to do so.
Bios: B75MD3H (F15)
