Can you remove spells from the spell selection screen at character creation?

I am making a rework of the Identify spell, but because of engine limitations I have to make a new Identify spell instead of just altering SPWI110.spl. How do I remove SPWI110 from the spell selection at character creation, so I don't have two Identify spells showing up. Overwriting SPWI110.spl with an empty file works, but then the game crashes when you click the identify button of an item.
