Is there a way?

if you mean not display the forum in forumdisplay, this can be a bit tricky, but if you dont have any problems with its name displayed to everyone, but they just cant enter there then you need to add the code to forumdisplay.php

find:

PHP Code:

$getperms=getpermissions($forumid,-1,-1,$foruminfo['parentlist']);
if (!$getperms[canview]) {
  show_nopermission();
} 


After that add:

PHP Code:

if ($forumid==X AND (int)$bbuserinfo[field5]<=Y) 
{
show_nopermission();exit;
} 


Replace X with your forumid and Y with points
