Renege a T2 signed contract for a T1

Hi all, I am a QR in Singapore with a few YOE at a small pod shop and currently serving my NC after I signed a contract for a T2 fund and resigned from my previous pod shop.

Funnily, I got approached by a T1 and passed all interviews. Now I want to renege the T2 but I wonder if they can stop me from joining the other firm given I have signed a contract already? Would the NCC be enforceable in any way even if I have not started my employment (it’s in a few months) or would they request any compensation?
