[Modding][Question/Request] Tech

Is there a way to make a tech impossible to trade to/by a specific race?

Examples:

This tech cannot be traded to this civilization.

This tech cannot be traded by this civilization.

*

Is there a way to make a tech gives malus/bonus to relations (diplomacy) with other civs if researched?

Per example, if this tech is researched by civ A, civ A gets -2 to relations with civ X, and +1 to relations with civ Y.



***** If that is not possible, consider it as a request. *****
