【Solved】Change Default selection on auto installation plugin?

[longpanda]

Currently this is not supported. 
Maybe you can consider the following workaround.
offer another empty or invalid unattend.xml.

Code:

{
    "auto_install": [
        {
            "image": "/Windows10.iso",
            "template": [
                "/script/fake_unattend.xml",
                "/script/real_unattend.xml"
            ]           
        }
    ]
}

Now fake_unattend.xml will become the default highlighted selection.
