I found the official documentation webpage for the StarFive Vision Five 2 Software, which explains how to deploy all the 14 assets of the Vision Five Software current version (VisionFive Software v3.7.5 Release) to get a working kernel and basic debian system at VisionFive 2 Single Board Computer Software Technical Reference Manual resp. VisionFive 2. It would be nice though to have a debian package for installing the respectively new kernel as it is quite tedious to reformat the SD card for every new kernel version especially, when one has already made the debian system comfortable for the previous version.
