If you want to continue to use the :split command, the swapExists
autocommand event can be used to detect the warning condition and
the v:swapchoice variable set to specify the desired action, e.g.,
autocmd SwapExists * let v:swapchoice='o'
Or you could just open the file using the :sview command which is
the same as using :split but also sets 'readonly' in the new buffer.
See
:help SwapExists
:help v:swapchoice
:help :sview
