Is it possible to disable default /vagrant synced folder?

Question

According to source code - it's not, but what if I'm wrong?

So the final question: is it possible to run a vagrant VM (virtualbox-driven) without /vagrant synced folder?

Answer 1

Yes. In the Vagrantfile:

Vagrant.configure('2') do |config|
  config.vm.synced_folder '.', '/vagrant', disabled: true
  # ...
end
