Here's definitively how to change your system name in MacOS across all components.
These instructions for modern versions, worked perfectly on Sequoia 15.4.1

sudo scutil --set ComputerName "odyssey-redux"
# Hostname (shown in Terminal prompts, network identification)
sudo scutil --set HostName "odyssey-redux"
# Bonjour/local network name (e.g. My-MacBook.local)
sudo scutil --set LocalHostName "odyssey-redux"
# Flush DNS cache to make sure changes stick
dscacheutil -flushcache
