In case anyone prefers to use Ventoy, I believe that I used Ventoy to install Daedalus-based Refracta on a Lenovo notebook. That being the case, I suspect that the Devuan desktop-live ISO, and maybe the Devuan minimal-live ISO, would also work.

There is no magic involved.
Installers that are fully contained within their initrd will be fully loaded by ventoy from their ISO files, and "work" provided that they don't require access to their media.
Installers that require access to their media will not have that access, because the media is not available as partitions with ventoy.
If such an an installer is made to look for a ventoy partition, to mount that filesystem, to search for their ISO among the collection of ISO image files, then it may well also work.

From any Linux, use any USB stick that large enough for the iso and can be overwritten, and use cp or dd to the raw device, i.e. /dev/sda. Not to a partition like /dev/sda1.

Interesting, didn't know that cp has a device mode. Fist thought was you ment cat, which equally works here.
