Bootcamp ImageInstall Issue with Multiple Physical Drives

I have upgraded my iMac 27inch 2019 Fusion drive to 1 SSD and 1 HDD inside.

Before I upgrade my device, bootcamp worked with no problem, but now I cannot install win10 in my iMac. The error message was


Windows cannot locate the disk and partition specified in the unattend answer file’s <ImageInstall> setting. Make sure the setting references a valid partition and restart the installation


I know if iMac contain multiple physical drives inside, bootcamp have some problems by google searching. But I cannot reopen my device to remove my HDD now. Is there any way I can install win10 on my device?


I think what cause the problem is that I have installed macOS on my SSD and after I used bootcamp, I found C disk was set to my HDD. Maybe bootcamp has set C disk to install win10 but main system was in SSD (which is D disk). So I have tried unmount HDD while bootcamp installation and win10 installation but it did not work. I also have tried to install win10 without bootcamp with win10 install USB, which also did not work.

iMac 27″, macOS 11.5
