No. (But see * below...)

`dnssec-enable` is to do with handling of DNSSEC records and query flags:
setting and recognizing the DO flag and returning RRSIG and NSEC(3)
records in responses, etc. It's necessary if the server is authoritative
for signed zones, or if it is validating, or has clients that validate.

In general you should not have the `dnssec-enable` option in your
configuration file unless you are doing something very strange: leave it
out, the default is correct.

(*) It's possible that if you have broken middleboxes in your network,
your DNS server will not be able to make DNSSEC queries. If so, get the
network fixed :-)
