Would it be something different than "-a_nodata none"?

-a_nodata value:
    Assign a specified nodata value to output bands. Starting with GDAL
1.8.0, can be set to none to avoid setting a nodata value to the output file
if one exists for the source file. Note that, if the input dataset has a
nodata value, this does not cause pixel values that are equal to that nodata
value to be changed to the value specified with this option.
