The only way to not have GM/PM pets in your top 100 rankings, that I know of, is to not have top 100 pets on your GMs and PMs.
The game wasn't designed for GMs and PMs to have powerful pets during commercial server operation, and thus there is no feature to have them not be in the ranking. GM and PM characters are designed to function as close to normal players as possible, but with the extra ability to do other non-player actions. Otherwise it would be hard to test things with a PM character, when that's the whole point of having a PM character.. to test things.
