If you don't set the read authorization for the page or group
directly, you could add the following to your config file. $expires
should be the time when you want to end access and GroupName & its
length as you need them to be.

if ( !strncasecmp( $pagename, 'GroupName', N ) {
  $HandleAuth['download'] = 'download';
  $DefaultPasswords['download'] =
    ( $Now < $expires ) ? '@limited' : '@lock';

Note that by default uploads are stored per group but accessed per
page, meaning that by default if a user has read access to any page in
a group they can download any files from that group via that page. See
for my suggested fix for this.
