Which Plugin, and how?

[dimitrirodis]

I have a PPKG file that I would like to have automatically detected during a windows 10 installation.

The current process is as follows:
Boot Windows 10 with Ventoy
When the OOBE screen comes up, we insert the USB stick with the PPKG file
Windows 10 completes its final configuration

What I would like to do:
Boot Windows 10 with Ventoy
Choose the PPKG file (or perhaps an autounattend.xml?)
Windows 10 installs/completes on its own

I know there is a plugin to do unattended installations, but I haven't found a way to "inject" the PPKG.

Any advice or direction is appreciated.
