Tried modding myself with phoenixtool and Acer certificate via VSS2 method, replacing both original SLIC 2.0+2.1 tables with only 2.1 table (otherwise, it will just add the third table behind the first two
). Opening such created image again with phoenixtool confirms there is just SLIC 2.1 table module, but flashing twice makes no difference according to RWE, still shows 2.0.
Attached are the Acer certificate, and the image I've modded.
Here is the original to be downloaded from driverscolelction:
