Change network name (/etc/samba/smb.conf)

Hi,

I like to change the network name of my LibreELEC system to another one.
I logged in via ssh found the smb config file and directly noticed that the filesystem is booted in read only mode

How can I change the network name (or other smb related configurations) now?

Thanks for Help!
