No, this is not possible in a simple way.
Anyway, you may use a set of config files like this:
bird.conf:
...
include "apache-check.conf";
...
apache-check-yes.conf:
static apachecheck { route XYZ };
apache-check-no.conf: empty
apache-check.conf: symlink to apache-check-no.conf
write a script like this:
* if the condition is true: ln -sf apache-check-yes.conf apache-check.conf
* else: ln -sf apache-check-no.conf apache-check.conf
* if the script changed the symlink, reload bird config
and run the script by cron every other while.
Hope this is clear enough to help you.
