dhcprelay still listen on excluded interfaces

[IMMO WETZEL]

I do specified the upstream and downstream interfaces and
But still the relay is listen on the other interfaces of the host.
It drops the request, offers, disconnects and so on but still listen.

Is there a way to exclude all not important interfaces completely?

Background I do have a software switchrouter on linux base which has nearly 100 vlan interfaces on a single 10G link.
Onlz a few are routed . the most is switched. This could help a lot to reduce the overwork.
