I now re-installed Trixie as before and actually activated "GRUB_TERMINAL=console" in the GRUB configuration when I rooted into the new system but it unfortunately didn't alter the result. I still get just the Libreboot background image when ever I attempt to boot from my local SSD. And I did check if my change did actually persist by rooting into the system after my failed attempt to boot post change. I found some information on updating Libreboot but so far I was not successful in understanding how to do this without special purpose hardware. It seems it should be possible but I didn't find a guide I could actually follow yet.
