I haven't seen that Certbot can do DNS challenge. Well that simplifies my situation I believe. I will try it right now and come back with a response!
It depends on how you installed Certbot, which version you have, and which DNS provider you use.

Are you guys still on track to release ACMEv2, wildcard, and a compatible Certbot by February 27?

Are wildcard certs available now, since yesterday was February 27th? Where can the details/documentation for that be found?
