    I found three methods. I'm listing to help others if they need:

    First Method:

    sudo tee -a /etc/init/tty{1..6}.override <<<"manual"

    Second Method:

    Open/create the file /etc/X11/xorg.conf using the following command:

    sudo -i gedit /etc/X11/xorg.conf

    and add the following lines inside:

    Section "ServerFlags"
    Option "DontVTSwitch" "true"
EndSection

    Third Method:

    sudo -i

vi /etc/default/console-setup

    change ACTIVE_CONSOLES="/dev/tty[1-6]" to your choice. Lets say if you want only two TTY or virtual console then change to ACTIVE_CONSOLES="/dev/tty[1-2]"

    cd /etc/event.d

    Comment on all the lines in ttyX file that you don't need. In this example tty3-tty6 Reboot to see the change.

  3. sudo rm /etc/init/tty*.conf

    This will totally remove the tty* conf file and thus you will not be able to use it :)

    NB: you can't be able to restore it later on

  4. open the tty conf in the /etc/init/ directory

    comment out those lines in the ttyX.conf files: 

    #respawn 
#exec /sbin/getty -8 38400 ttyX

    Example to disable tty1:

    sudo -H gedit /etc/init/tty1.conf

    Then edit by inserting # in front of the commands

    #respawn 
#exec /sbin/getty -8 38400 tty1

    Save and Reboot

  5. On Gnome Wayland you can unset the keybindings for virtual terminal switching by setting these dconf properties:

    dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-1 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-2 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-3 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-4 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-5 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-6 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-7 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-8 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-9 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-10 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-11 "['']"
dconf write /org/gnome/mutter/wayland/keybindings/switch-to-session-12 "['']"
