Pm.set_data in 4.2.0

If you make the observed data mutable data:

    obs_data = pm.Data("obs_data", value = y_train, mutable = True) 
    observed = pm.Bernoulli("indicator",
                            pm.math.sigmoid(beta_0 +
                                            beta_1 * first_feature +
                                            beta_2 * second_feature
                            ),
                            observed = obs_data
    )

and then swap the observed data:

with logistic_model_pred:
    pm.set_data({'first_feature': X_test['first_feature']})
    pm.set_data({'second_feature': X_test['second_feature']})
    pm.set_data({'second_feature': X_test['second_feature']})
    pm.set_data({'obs_data': y_test})
    ppc = pm.sample_posterior_predictive(trace = pred_trace)

I think it should work?
