Ubuntu server live installer vs ubuntu server preinstalled image for nvme ssd

Was looking into installing an updated version of ubuntu on an unmatched rev b device using nvme ssd as storage. Went to the distribution site here: Download Ubuntu for RISC-V Platforms | Ubuntu

and saw this quote next to the “Ubuntu Server preinstalled image” for unmatched rev b boards :

“If you have an NVMe drive, we advise you to use the Ubuntu Server live installer.”

Is there a specific technical reason why ubuntu suggests using the Ubuntu Server live installer versus the preinstalled image on an nvme ssd drive?
