There’s several shared and confirmed SPI image files on the Badcaps thread you posted.
Now…upon extracting the latest original Dell file i see MTL and RPL, your’'s a MTL system based.
You can ty to exchange volumes from this extracted Dell file (bios_region), reconstruct the image and re-initialize CSME v18, mFIT @ post#331

As reminder, already noted on same forum… the GD25LR512ME is a 1,8v IC
