Any one make any attempts on unlock CPU cores/ threads or iGPU CUs on AM4 ?

As in topic, for example on Athlons, Ryzen 3 2200g /3200G or Ryzen 3 4350G/ Ryzen 5 3500

I understand that they most likely Laser cut blow fuses to disable cores / CU but I wonder if is possibility they forget about something maybe SMT?

I simply wonder if everyone assume AMD disabled all functions on hardware level, and we do not have any attempts to test it ?
