HGST WinDFT doesn't see AHCI drive

I have issue that Hitachi WinDFT AHCI/IDE/USB 0.95 (Drive fitness test for Windows) does not see AHCI internal drive on HP ENVY 17-j010sa Notebook with Windows 10. The BIOS does not allow to set it to IDE mode so option other than AHCI. Found there is a WinDFT.ini configuration file with entry hitachiHdd=1 but it doesn’t change anything if set to 0 or 1. Help opens up a blank page with just "DFT for Windous (help.txt) is also very explanatory with only one line written with mistake.
