yes, pd's [spigot] can "gate" message-flow.
using to parallel (one with inverse logic) [spigot]s will do what you
want. (refer to pd's manual)
another way is zexy's [demux], which demultiplexes one message-stream to
one-of-many branches.

and you can turn on/off most (i'd rather say: all) [pix_]-objects by
simply sending 1/0 to their leftmost inlet (the one, the GemList goes into)
me, i use [demux] for your kind of problem (because of personal likings)
