Is Entity Recognition pipeline component required/used for Intent Classification?

I am using a separate entity recognition engine but would still like to use RASA for intent classification. Will disabling the Entity Recognition step in the pipeline affect the intent classification?

in earlier versions of Rasa, intents and entities were always fully independent. But with the new model, DIET, you have the option of training both, or just one of the two, see Introducing DIET: state-of-the-art architecture that outperforms fine-tuning BERT and is 6X faster to train

But yes, you can always just use Rasa for intent classification and use a different system for NER
