How to know if domain has been setup with auto renewal with Let's Encrypt

I hope you haven’t setup the hostname as a domain in virtualmin, you don’t need to do that.
Set your hostname to something like server.mydomaim.com and then just host mydomain.com in virtualmin

if you have delete that domain from virtualmin
and

@vminh

So I can forget about the SSL cert of the system hostname domain, right?

yes
