I don't think so.

According to the Evo Help, the regexp follows grep(1) syntax. Grep can
search for case-insensitive patterns if invoked with the "-i" flag, but
has no built-in way to express case-insensitivity as a pattern (other
than laboriously giving every upper and lower case alternative as in
[Pp][Aa][Tt][Ee][Rr][Nn]

Note that grep itself can de told to default to case-insensitive by
setting the environment variable GREP_OPTIONS="--ignore-case", but I
don't think that will affect Evo. Perhaps a Request For Enhancement is
in order.
