i did think that you can still do it as long that you don't get 2 point not 1 or 2 and trying to find the value by playing class and getting 1 star and leave the class by using gems then go to another class with 3 start at least and getting 1 star then leave using gems will make you lose at least 1 house point untill i find the valueTo edit/freeze house points for your house, you can edit your characters points but not the house total. Although I assume that you are asking to avoid getting sorted for house pride, to which the answer is that you used to be able to but not anymore.
Back when you needed 15 house points to get sorted, you could find the value for house pride and then lower it back to 0 or just freeze the value for that current session so that you didn't reach the threshold to get sorted into a group.
However now that you need only 1 or 2 points to get sorted it is no longer possible, as to edit the value in gg you need to search and increase the value at least once to find the correct one, which is not possible without exceeding 2 points and getting sorted.
