Is there a easy way to turn off/ Disable the DNS server to stop
listening the requests over TCP and turn it ON whenever required?
no and it does not make sense at all
tcp is required for:
* zone transfers
* EDNS
if it ain't broken don't fix it
to make it clear - i was years ago taht stoopid too and opened TCP only
for the machines doing zone transfers but we saw random resolution
errors reported from users which ever appeared again after open port 53
for UDP and TCP and that was long before EDNS and DNSSEC where a topic
like these days
