EDNS0 is compiled and supported in BIND by default.
You only need to check if your settings or firewalls don't block DNS without
EDNS0 

you can test your zones on https://ednscomp.isc.org/ednscomp

according to information https://dnsflagday.net/, your client should not be
blocked from sending EDNS queries.
