Add the following to your kernel config file and re-build your kernel
options SC_DISABLE_REBOOT # disable reboot key sequence
Alternatively, edit /usr/share/syscons/keymaps/<your_keymap_file> and
change all instances of ``boot'' to ``nop'', e.g. from
083 del '.' '.' '.' '.' '.' boot boot N
to
083 del '.' '.' '.' '.' '.' nop nop N
