Correct DJI Terra Orthomosaic Output - 0 value in RGB is Nodata

Remote Sensing

Hi,

When using DJI Terra to ouput a stitched orthomosaic, the resulting tif orthomosaic file comes with a nodata = 0 flag (1). When displayed in QGIS, this results in holes in the raster in dark areas, where any back has a value of 0 (2). I can delesect the nodata value option to view these dark areas (3), but when I perform an operation such as 'Easy Raster Splitter' (5) to divide the raster up into sections, these holes are doubled down on by the alpha channel becoming 0, as opposed to 255 (6).

I just want the black areas to be black, with 0,0,0,255 if necessary. Is there a way to just remove the nodata tag?
