How to bypass VPN for Instagram and WhatsApp traffic

Hi there I use wireguard client to connect to VPN on my AR300M. I don’t want traffic for certain services such as Instagram and WhatsApp to go through the VPN. How can I add exceptions? Is there a way to add all hosts those apps connect to to the router’s VPN policy?

Should you add all facebook’s servers?

Technically yes but how can I find all their servers?

will separating your devices into lan network and guest network for local traffic and vpn work?

A quick google search:

Thank you so much but I’m pretty sure there are more hosts for example fbcdn.com
