Location of device name

I have 3 Libreelec Pis setup. I often make changes on one and then copy everything to the others. I then manually have to go to the devices and change the device name in 2 places. One in Kodi settings and one in Libreelec settings. I am wondering if these are in a text file I can just update or if I can avoid copying this file(s) with the device name.

Pretty much everything. I want my skin settings, custom menus, any other settings, wallpapers, addons, addon settings, etc. I restore the backup to the other PIs essentially. I want to exclude (or later modify) the files with the device name.

/storage/.kodi/userdata/addon_data/service.libreelec.settings/oe_settings.xml <= OS

/storage/.kodi/userdata/guisettings.xml <= Kodi

Thanks!
