You can disable them per /etc/periodic.conf (see examples in
/etc/defaults/periodic.conf). To keep the functionality, but
restrict it to a smaller amount of files, you could use the
system's scripts as templates, make your own "derivates"
(wich inclusion or exclusion rules) and place them in
/usr/local/etc/periodic for the system to call them (which
it will if they are present). You can add your custom
configuration flags to /etc/periodic.conf and have your
scripts source that file (like the system's scripts do).
