singel iso file to boot

[aboamir@gmail.com]

I Need a specialized setup for a single ISO file such that it can automatically boot instantly when a USB drive is connected to any device. It is essential that this process occurs without showing any pre-boot screens, like those provided by Ventoy, to the end user, ensuring a higher level of security and maintaining the privacy of technical system operations.

PS :{ "VTOY_DEFAULT_IMAGE": "/iso/myiso.iso" }
