Re. "
what kind of strings attached to Rafale or it's completely string free and about the stealth will dassault let us modify the air like that fuel probe or like US you will tel us you can't do this do that and so on, what i mean is what is policies regarding Rafale."
You can remove that fixed refuel probe and find out the gain in increasing the range at which you are detected is pretty marginal. To produce a meaningful reduction in RCS you would have to scrap the whole thing and start again from scratch.
The flight control system, navigation, terrain-following radar and avionics are highly integrated and safety critical systems. It is highly unlikely the original design authority will be transferred to a licensee. The unstable nature of the platform adds a further layer of complexity.
In theory you might be granted some freedom of manoeuvre but in practice--given the nature of the Rafale design--you will have to go back to the original design authority.
