So I found on [ubuntu.manpages](https://manpages.ubuntu.com/manpages/xenial/man8/flashrom.8.html#programmer-specific information) the following under AMD Chipsets:
`
Beginning with the SB700 chipset there is an integrated microcontroller (IMC) based
on the 8051 embedded in every AMD southbridge. Its firmware resides in the same
flash chip as the host's which makes writing to the flash risky if the IMC is
active. Flashrom tries to temporarily disable the IMC but even then changing the
contents of the flash can have unwanted effects: when the IMC continues (at the
latest after a reboot) it will continue executing code from the flash. If the code
was removed or changed in an unfortunate way it is unpredictable what the IMC will
do. Therefore, if flashrom detects an active IMC it will disable write support
unless the user forces it with the
flashrom -p internal:amd_imc_force=yes
syntax. The user is responsible for supplying a suitable image or leaving out the
IMC region with the help of a layout file. This limitation might be removed in the
future when we understand the details better and have received enough feedback from
users. Please report the outcome if you had to use this option to write a chip.
`
Is this applicable, and if so, is there some plausible workaround?
