Thank you! This fixed my problem.
I had to use this link https://forums.plex.tv/t/writing-profiles-for-dlna-devices/38060 to find out how to write DLNA profiles and it just says
User profile files are located in the Plex Media Server user directory, in a directory called Profiles.
So I assumed it was in /usr/. Although it is very outdated (2013).
Thanks again!
