react-hook-form batch async validation

Say I have 3 separate fields in my form and I want to validate them asynchronously, i.e. by sending a request to the server. Currently, I am doing this manually on the submit handler. I know you can define your custom validate() function for registered controllers, but that would cause 3 separate requests to be performed.

How to batch them together so there is only one request for all three fields?

You have to set mode in useForm to "onSubmit" to make the validation trigger on the submit event.

useForm({
    ...
    mode: "onSubmit"
})
