You can *restrict* the client to a subset of the channels
certified
for use, but you can not *expand* the set of channels.
Meaning, if you have a client that can tune to channels 1-13
and you
go to a region that only supports channels 1-11, you should
be able to
tell the stack not to use channels 12 and 13 (I don't know
if you
currently can; adding a parameter to "disable" a
set of channels seems
like a reasonable request if a mechanism does not already
exist to do
that.)
However, if you have a client certified only for use on
channels 1-11,
and you travel to a region where channels 12 and 13 are
available, you
should not change the client to try and use channels 12 and
13.
