Hi @<1694157594333024256:profile|DisturbedParrot38> ! If you want to override the parameter, you could add a DiscreteParameterRange to hyper_paramters when calling HyperParameterOptimizer . The DiscreteParameterRange should have just 1 value: the value you want to override the parameter with.
You could try setting the parameter to an empty string in order to mark it as cleared
