i figured out how to remove shared "bandlab" plugins.
after generating a scanlog of my VSTs (of which sonar added over 1,000!!!!!!!) i found that the shared bandlab vsts come from a file called "BandlabVSTShell.vst3.
SO.
if you go to this address in the screenshot and simply delete that vst file, they will all go away and stop clogging your memory :)
