I really don't think this is possible. Once an interface is made part
of a bridge it stops being it's own unique device and starts being part
of a whole. You can't effect one part of the bridge without the other.
The only possible way to attempt it is to use the V3.0 with this setting:
/interface bridge settings set use-ip-firewall=yes
Then to setup an input rule:
/ip firewall filter chain=input protocol=udp dst-port=67
in-interface=ether1 action=drop
But I don't think this would work in the instance of a bridge. If it
wasn't bridged it would cause the ethernet interface to ignore all DHCP
requests.

I assumed that the DHCP server would "listen" only on the interface it is
configured. The ip firewall rule does nothing, in fact I cannot get the ip
firewall to log any packets.
