LE cert renewal using Nginx for Synology wildcard

[Telos]

My Synology DDNS wildcard cert needs to be renewed. I was curious if this can be done via NPM docker. My private domain wildcard was set up on NPN, but it required an API. How would I obtain an API for my Synology DDNS... is that even possible? Or is there another way.

Of course, I can renew the LE cert via the NAS itself, but I hoped to manage all certs in one place.

Thanks in advance.
