Looking through the vim source, it looks like that message can only be suppressed when launching the executable as ex and using its -s option, or by not having a console.

Neither approach will work for diffing.

However, the message is only output if there is more than one file specified on the command line.

So let's trick it:

vim a -c "vert diffsplit b"

Which basically says "Edit file a with vim, and once a is loaded, open a vertical split with file b and diff them".

--not-a-term option can suppress the message.

vimdiff --not-a-term a b

Document :h --not-a-term
