Thank you Stephan!
I don't know about that tool. Maybe they have a mailing list?
It is possible the area is write-protected, but it's only a guess.
flashrom has an entry for Elkhart Lake:

Hello Arvind,
My question is, which tool are you running? This doesn't look like flashrom.
We don't have `flash_erase` command, and no `mtd_erase_multi` function.
And I don't recognise the printed messages.

Hi All,
We are trying to implement the flashrom tool utility on the x86
*Elkhart Lake*(LEC-EL) platform. In this case, we are facing an
issue when trying to erase the BIOS device MTD0. There are 4096
erase blocks available in the mtd0 device, but only 1791 erase
blocks we can erase; the remaining blocks are throwing errors, and
it shows MEMERASE64 IOCTL FAILED. Please see the below error message
and MTD0 device info for your reference.
NOTE: Sometimes it works; we can erase the MTD0 device without any
error, and we can upgrade/downgrade the BIOS.
