FactoryBot.modify does not override gem factory

[Set27]

Description

I tried to get all factories from spree gem, but overriding some of the factories, in this case user factories. I add it them using require 'spree/testing_support/factories'inspec_helper.rb`.

But

Using FactoryBot.modify I get

  Factory not registered: "user"

Using FactoryBot.define I get

  Factory already registered: user
