smb.conf does not come by default on any EnOS installation.
Here is a smb.conf file that I use for headless EnOS LAN servers. Works for my purposes on both x86_64 and aarch64 ARM.
In a terminal window, in a Temp folder
wget https://github.com/pudges-place/scripts/raw/main/smb.conf
Then copy it to the /etc/samba/ folder on the Linux device you want to act as a Samba Server.
The last eight lines of the smb.conf file define your Samba share
