Conditional AllowedSignUp on Lock

[slance]

I was able to solve the problem a little bit after I asked the question with the following code before lock was instantiated:

var allowSignUp = false;
var signUpLink = '';

if (config.clientID == '<client id>') {     
  allowSignUp = true;
  signUpLink = 'account/register';
}

var lock = new Auth0Lock(config.clientID, config.auth0Domain, {
    ...
    allowSignUp: allowSignUp,
    signUpLink: signUpLink,
    ....
}
