Is it possible to access part1 during installation?

Hello ventoy developers. Is it possible to access the part1 described in ventoy doc during the installation of an OS? I got an "device or resource busy" after trying to mount the partition 1 in debian 11.

It would be helpful to load some files when installing OS, for example some firmware. I am aware of creating another partition to hold the file, but it is not flexible and the partition size may not be desirable in the future. Thus, I want to put all files in one partition and that is the problem.

Anyway, thanks for your help in advance.

The latest Ventoy 1.0.64 provides an experimental option VTOY_LINUX_REMOUNT which can help to access the ISO partition after boot.
