I used to use Drumagog to do all that.
I looked for a free Mac plugin, I tried it with the ride track and I could filter out the snare https://a1audio.alexhilton.net/downloads
BUT it's a vst3 on Win so you can try the Mac one and see if it's the same or they might have one that work directly in BBMac ?
It will work in your DAW.
In Logic you should have a Gate with ducking so you can invert the signal to let the low level through.

EDIT: I had another look and there are VST2 there also, so you should be able to try the in Biab.

Look at Element, you can drop VST3 Plugin in it inside Biab (just enable EXT top left for sync)
