How set aperture with NXL speedbooster?

Hi guys,

I was offered an NXL speedbooster, built by Luca in Italy. I read great feedback online about its build and optical quality. However, it is a dumb adapter without any electronic connections in it.

So my question is: how could one set the aperture for Canon lenses (or any other lenses for that matter) that lack a manual aperture ring?

My main goal is to use it with an wide angle zoom lens, like the 16-35mm. But modern lenses do not have an aperture ring...

Thanks in advance!
