As mentioned on the MCU Bootloader Manufacturing Tool User's Guide:
"The MfgTool for MCU devices is bundled together with the MCU bootloader in <sdk_package>/middleware/mcu-boot."
That means that you can find the MfgTool under the RT1170/1020 SDKs, and following the paths that are mentioned on Chapter 2 of this document.
