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
         id 00:00:00:00:00:00 priority 32768 hellotime 2 fwddelay 15
         maxage 20 holdcnt 6 proto rstp maxaddr 2000 timeout 1200
         root id 00:00:00:00:00:00 priority 32768 ifcost 0 port 0
         member: tap0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
                 ifmaxaddr 0 port 5 priority 128 path cost 2000000
         member: bge0 flags=143<LEARNING,DISCOVER,AUTOEDGE,AUTOPTP>
                 ifmaxaddr 0 port 1 priority 128 path cost 55
