Wild card for main domain and subdomain

I have dev eks cluster where dev, qa & stage environments are running and prod eks cluster where production environment is running.

We are using Traefik v2 on dev eks and get each subdomain to get its individual certificates (*.dev.domain.com, *.qa.domain.com, *.stage.domain.com) which works.

But on production via Traefik v2 will I be able to get wildcard for main domain (*.domain.com) ? If Yes do I need to provided same email as other subdomain ?
