Sure, no problem.  Let's suppose you want to disable page history
for XYZ.SomePage .  Simply create a file called local/XYZ.SomePage.php
that contains

    <?php
      $DiffKeepDays = 0;

Whenever the page is updated, any page history information older
than zero days will be discarded.  Repeat this for the other
two pages.

Or, if you want to handle it all from local/config.php, you can do:

    $pagename = ResolvePageName($pagename);
    if ($pagename == 'XYZ.SomePage')  $DiffKeepDays = 0;

Of course, you can set $DiffKeepDays to some value other than zero
if you want to keep some history but not as much as PmWiki's default
setting (ten years).
