Title:
  Ubuntu ISO booted from Ventoy: Hide the Ventoy device from "Select
  drive"

Status in subiquity:
  New
Status in ubiquity package in Ubuntu:
  New

Bug description:
  Facts:
  * When a dedicated Ubuntu ISO is installed on a USB flash sticks (for example ubuntu-23.04-desktop-amd64.iso via usb-creator-gtk), the USB device will not be listed in the "Select drive" during the Ubuntu installation.
  * Ventoy issue: If you add a Ubuntu ISO (or several ISOs) to the multiboot ISO tool Ventoy, the USB device will be available in the "Select drive" during the Ubuntu installation. Ubiquity will list the largest device first.

  Step to reproduce the Ventoy issue:
  * Download a Ubuntu ISO
  * Download, and install Ventoy (https://github.com/ventoy/Ventoy/releases) on a USB device.
  * Copy the Ubuntu ISO to the VENTOY partition.
  * Shut down the computer.
  * Boot the Ventoy USB device, and select the Ubuntu ISO to start the installation

  See Bug attachments for screenshots.

  The same issue will be reproduced if you run Ventoy from a SATA SSD
  without USB adapter.

  For comparison
  * Windows 11 (Win11_22H2_EnglishInternational_x64v2.iso) will correctly NOT show the USB device if is installed from a USB device with Ventoy. See screenshot.
