I don’t know if it’s something you want to tackle, but making a separate VLAN on your home LAN and shifting all the IoT/smart devices to that network can keep them from whatever snooping or spying these devices might do on your LAN that you work and live on. Plus you can more easily monitor the unreasonably chatty ones and block them or at least prune off their ad-seeking IP addresses. PiHole for a home LAN can help a lot too, but that’s another discussion.
