Yes, you can write to the dataflash (including Manufacturer Info Blocks) in HDQ mode.

However, keep in mind that there is a dataflash parameter called "Flash Update OK Voltage" which defaults to 2800mV and if the BAT pin does not have a voltage at least this high on it then the gauge won't let you write to dataflash.
