Can not install Win 10 (Bootcamp 6.1)

I did a fresh osx install and wanted to install window 10 back but bootcamp is asking for a usb drive, high sierra wasn't asking it, win10 iso file was enough. Even I try to install with fat formatted usb drive, I still can not install. (Note: I have a default fusion disk came with iMac but not using it. Installed 500gb ssd.)

See the screenshots:

Trying without USB connected . I wasn't asked for a usb when I was on high sierra in same computer. Want to install to 500gb ssd(macOS container) :

Trying with a fat formatted USB disk:

Also tried the way without bootcamp as described here: https://fgimian.github.io/blog/2016/03/12/installing-windows-10-on-a-mac-without-bootcamp/

and again no luck :

I don't want to downgrade to high sierra. What should I do?

I did NVRAM, PRAM, and SMC reset

Run

diskutil eraseDisk jhfs+ HDD disk2

To build a base APFS container, run (the -main and -secondary qualifiers are required to do this correctly).

diskutil apfs createContainer -main disk0s2 -secondary disk2s2

A TM Restore should rebuild the volumes, but APFS can be 'flaky'.

Do you have a backup of macOS? If yes, we need to rebuild the Fusion drive and restore the macOS side, before you can install Windows. The current configuration will not work under Mojave.
