Unless I'm mistaken, this message will only appear if the buffer or the
file has been modified.

Do you want to switch to the existing buffer, or create a new buffer?

If it is the latter, this answer should do it:
https://emacs.stackexchange.com/a/52513/184

If it is the former, and assuming that you want to show the on-disk content
of the file, find-file-noselect has a 'nowarn second argument disabling the
prompt.
So (switch-to-buffer (find-file-noselect FILE t)) should work.

confirm-nonexistent-file-or-buffer seems to be about the opposite problem,
whether to query when the file/buffer does not exist, rather than create a
new one.
