For a Server environment to change the keyboard layout is possible use the sudo localectl set-keymap <keymap> command in peace. Other approach would be with TUI (Terminal User Interface).
You should normally access the server over SSH and it follows the client settings.
Direct access should be limited to emergency cases that can be resolved with sane defaults, and then you can use SSH again.
According with my understanding your are correct about the loadkeys command, it works for the current tty (perhaps I am wrong) but the sudo localectl set-keymap <keymap> is global

Thanks for the suggestion, but It is for a small LAN with SSH and throughout the day according with a schedule some members need change the keyboard layout. Again, the localectl set-keymap works fine but just wondered if TUI can be applied as the Figures available in the link provided.
For example Debian and Ubuntu have the dpkg-reconfigure keyboard-configuration command
