When adding noise to audio data in order to dither it into lower bit depth, should the noise be added to higher bit than the desired outcome bit depth? For example when 24bit data is meant to be dithered into 16 bit , the white noise should be added between the 17th to the 24th bits of the original file?

I saw this plugin for foobar : foo_dsp_noise. With this plugin foobar can add TPDF noise up into the 24th bit but not higher. Does this mean it is usable only for dithering to 16bit and not to 24bit output?
