How can I tell Bison, I also expect a reduction in contraction reductions?

Question

My C # toy grammar now has its first contraction-contraction conflicts! I am so proud of me.

Everything seems to be in order, however (I disconnected for the GLR analyzer about this). The problem is that although I know that the directive %expectcan plug Bison into shift / decrease conflicts, I cannot find the equivalent for decrease / decrease conflicts. So what should I use to silence him about my 3 shifts / contractions, and my 2 shrink / shrink?
