If you want to batch convert bitmaps to vector with the advanced "ignore white", there is also very simple solution to do that Here's how:
Open Illustrator (2020). Create a preset in Illustrator for tracing (goto "Windows > Image Trace"). I made a preset and called it "BW-No-White". The preset is set to convert to black and ignore white (= ignore white backgrounds).
Then open "Adobe Bridge". Within Bridge, go to the folder where you have your bitmaps that you would like to batch convert to vectors. Within Bridge, Select "Tools>Illustrator>Image Trace". Select your preset (which you set up prior in Illustrator). Set you destination folder and click OK. That's it. No need to script anything!
You can change your default image trace settings, by adding a custom script to it. Here is a link on how to do it: https://community.adobe.com/t5/illustrator/batch-image-trace-with-transparent-background/td-p/11210899?page=1
