My two yo is a biter at daycare

I have 25 mo twin girls. My twin B is a biter. She
used to bite TwinA but she stopped doing it at home lately. And they started going to daycare this April. It's only two month but teacher told me she bit her friend probably around 10 times already. It seemed like different kids each time. Teachers normally don't tell me who she bit but I was told who got bitten today. It wasn't that deep bite but I feel awful. I keep telling her we don't bite, hit or push anybody. I give her time out when she does those at home. But I feel there's not much I can do what she does at daycare tbh. Is there any advices how I can approach this problem? TIA!
