No, signaling in SCG is not allowed. Only MCG can handle the signaling. i don't know the reason why this restriction but spec says it is not allowed. All signaling should go via MCG and MCG will transfer the particular request to SCG.
As per my understanding UE doesn't require to send an signaling to SCG because all context transfer happened via X2 interface between MCG and SCG.
