Yes. As far as I understand, Traefik picks an appropriate certificate based on the domain for which the certificate was issued. So if you have two certificates, one for \*.example.com and another one for \*.website.com and you visit [dashboard.website.com](http://dashboard.website.com), it will automatically pick a certificate for that domain.
