VPB doesn't provide any direct support for setting which values to ignore, but does check GDAL's GDALRasterBand NoDataValue, not all image file formats will support a NoDataValue. You'll need to check with GDAL to see what is possible. If it's image data you want to blend together then using RGBA image data will allow blending between image layers that can effectively mask out the no data areas.
