I don't think you can do that directly (not without a lot of hacky tricks, at least). Usually it is better to use a bonus system and trigger all your bonuses yourself instead of relying on the game. Those systems will then usually let you read all the bonuses provided through the system.

For heroes, it is easy if you are using the game's default stat system. Calculate the base armor from agility and then subtract the base armor from the armor you get from BlzGetUnitArmor to get the bonus armor.
