I do this too, have acls setup for my main LAN ips and all my internal hosts setup in opnsense in hosts override so they get redirected to NPM. Not sure if this is the correct way but it gives me all valid certificates. You could also do domain override and redirect just that domain to your NPM.

Nginx Proxy Manager is awesome for managing certificates. I have all of my services running behind it.
