I think you have removed some # comment characters which you should not have. This is what the 'Freedom to advanced fonts control' patch should look like for firmware 4.15.12920:

Freedom to advanced fonts control:
  - Enabled: yes
  - Description: |
      This patch allows the advanced font options (weight/sharpness adjustments)
      to work with sideloaded fonts too. (KEPUB: OTF and TTF. EPUB: TTF only.)
      Beware unknown side-effects for Japanese or Chinese language books.
    #
    # The following passes a junk pointer to N3FontTypeUtil::setupDropdown, but it
    # seems the pointer is only passed on to ReadingSettings::getDefaultFontFamily
    # where the code is patched to avoid dereferencing it, so it should be safe.
    # BEWARE: What are the side-effects for Japanese / Chinese language books?
    #
    # N3FontTypeUtil.setupMonotypeDropdown(b,c)
    # --> N3FontTypeUtil.setupDropdown(UNDEFINED,b,c)
