Can we enhance threshold EdDSA to generate deterministic signature

[lucky1024]

After some tests, I found the signature is not deterministic.

Alice/Bob/Carol setup a (2,3) threshold EdDSA. With same input message, Alice and Bob generate signature X, Alice and Carol generate signature Y. I found X != Y, but in rfc8032, the signature is deterministic.

Can we enhance threshold EdDSA to generate deterministic signature?
