how to disable themes

[arniworx]

hi!
thanks for this great tool.
i've noticed that it runs a lot smoother, when i disable the theme (comment in grub.cfg)
is there an "official" way to disable theming?
a "ventoy.json" with the follwing content:

Code:

{
    "theme": {
        "file": ""
    }
}

brings up the default theme...so that's not the right way ;-)
thx
