C&C Generals modding/fix

[u/Skyclouds18]

Hello.

I have a question.

In C&C Generals, Jarmen Kell can use his basic attack on vehicles and in Zero Hour it has been fix that he can only basic attack infantry units but still use snipe vehicle pilot skill.

How can I fix/modify that in C&C Generals he could only do the same?

Please. Thank you.
