If Hahnemuhle Photo Rag paper might have problems with small particles of paper flaking off, is there merit to either brushing the paper off before printing, or maybe using an air blower or small vacuum, or just ignore it?
I very soft hand brush works. Also maintain humidity. That’s important. We use hepa filters in our studio as well to keep dust down.

Definitely don’t ignore them. Little white spots are a pain. And they will pop up just when you think they are all taken care of!
I’ve used a very fine brush - or actually just a few strands of a cheap brush - to fix little white dots. Just be sure to use the right shade, a magnifying glass less ink than you think you need. People used to use the old photo retouching inks as well.
Most important thing is to not brush the print right away. Let cure overnight and then brush
