There is no BOSE blocking list
My Bose Soundtouch speaker is directly connected to my home WiFi. Is it possible to add a block list for tracking Bose speakers?
Pretty sure there is no blocklist for it but here is a GitHub issue talking about Bose speakers and them hitting certain servers.
They blocked events.api.bosecm.com saying that it's the intial lookup that starts other AWS lookups so you can block that as well.
