DirectAdmin and cPanel both provide certificates for the server and then every eligible domain placed on the server.
cPanel provides 1 year signed certificates for the hostname (server) and then 90 day certificates for every eligible domain via AutoSSL (Sectigo) or Let's Encrypt.
DirectAdmin uses Let's Encrypt for everything, hostname, domains, etc -- all 90 day certificates.
I have one of your older VPS-2 accounts. Is it the same for that?
The only way you wouldn't be eligible is if your VPS was using CentOS 6 (32-bit) with cPanel as cPanel would be stuck to version 11.56 which is before AutoSSL was fully utilized and available.
When in doubt, open a support ticket and we'll be glad to check for you.
