Ok…since youre familiar with GRUB tool, take a look at UBU tool: [Tool Guide+News] "UEFI BIOS Updater" (UBU)
extract the mcodes from the 7D25V13 or get it from here: CPUMicrocodes/Intel at master · platomav/CPUMicrocodes (github.com), and update your current bios mod dump.
On UBU use the USER_mCcode folder and generate the mcodes present on current bios and newer ones/merged/replaced.
EDIT: Im not english native language “smth ofc”…
