We can’t discuss non-PG settings in this area, but you can check over in Beyond the Manual for lots of suggested settings for BB. That said, though, that’s just a starting point if you want to do super thin cuts like this.
I always dial in my settings for a new batch of BB using @evansd2’s method (see below). My goal for something this delicate is to find the settings that will cut through the wood and not totally through the masking on the back, which takes some fine-tuning.
