Ventoy may support the grub2 play command which will make the built-in mainboard speaker (if fitted) produce a note of a specific frequency for a specified duration.
In grub2 console type 'help play' on a real system (may not work on VM such as QEMU or VBox)
e.g.
play 400 900 2 1000 2 800 2 400 2 600 4
use google to find more tunes.
You could use F6 in Ventoy to make a menuentry to play a tune, but I am not sure how to make it autoplay on startup unless you modified the Ventoy grub.cfg file.
\ventoy\ventoy_grub.cfg
menuentry "Play tune" --class=custom {
play 400 900 2 1000 2 800 2 400 2 600 4
}
