Let's Encrypt vs PositiveSSL on VPS

[devzx]

Hello, dev pals:

I am having an issue trying to find some info about what to do next with my domain and its ssl/tls certificate.

Here's the situation: I got a VPS, and  I like to thinker with things on my own, like reading, researching, no-AI help, old school, and I  found out that installing Hestia was not that hard using their autoinstaller, but now, when I get to the part of activating the ssl certificate with the command they provide: v-add-letsencrypt-host, I realized the domain I already own,  has its own certificate from PositiveSSL.

To access Hestia CP,  since it is going to have a subdomain to my own domain, do I really have to activate the let's encrypt certificate, or can I just let it use the one I already own?

Thanks a lot in advance for your help and tips.
