follow the guide as written

you need to press f4 at the clover boot screen which will generate the file acpi/origin on your efi

then in terminal:
cd "to directory where you placed all SSDT/DSDT"
iasl -da -dl DSDT.aml SSDT*.aml

"directory where you placed all SSDT/DSDT"
is it the /EFI/clover/ACPI/origin ?

probably best to copy the origin folder to your desktop and use the desktop origin

I copied it to desktop and run the command.
