Just remove SYNCDHCP
For example:
cloned_interfaces="bridge0 tap0"
ifconfig_bridge0="addm bge0 up addm tap0 up"
It will create bridge0 with bge0 and tap0 as a members.
bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu
1500
ether 02:71:2c:00:ca:00
nd6 options=9<PERFORMNUD,IFDISABLED>
groups: bridge

maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200
root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0

ifmaxaddr 0 port 5 priority 128 path cost 2000000
