Your source is IDRW, this is not a trustworthy source. Trust me, AMCA will most probably not possess any kind of TVC.
And AMCA's design if you observe is more inspired by F-35 JSF. I don't see how the AMCA Looks any way similar to F-22's design.
See this :
This is design of F-35A.

And this is latest design of AMCA :

See how the latest design of AMCA has similar wing design, similar front nose section design, similar vertical Stabilizer design and also intake design? This shows it is more inspired from F-35 than F-22.
And BTW Why do you want AMCA to have thrust vectoring control in the 1st place? It's irrelevant for it to have it and being a 5th Stealth generation fighter, it should not have it and it doesn't suit IAF's doctrine. TVC is good for only dodging missiles and WVR Dogfights. Any 5th generation fighter which is being designed to be quite Stealth will always want to avoid getting into a dogfight.
