Azure B2C disable Sign up of a SignUpAndSignIn policy

I need some advice on Customising Azure B2C.

I've been looking at both portal based customisation and the Identity Experience Framework.

My key requirement is to have full control of the look and feel of the login experience. However, users must not be able sign up as this is handled by a separate business process. I understand that I cannot use a simple SignIn policy as B2C doesn't provide the required level of customisation.

I'm unable to find any solid documentation that describe how/if this is possible.

I've followed this documentation for the Azure B2C Identity Experience Framework. But can't see where I would be able to disable signup.

You can disable the sign-up button using the setting.showSignupLink metadata:

<TechnicalProfile Id="SelfAsserted-LocalAccountSignin-Email">
  <DisplayName>Local Account Signin</DisplayName>
  <Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.SelfAssertedAttributeProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
  <Metadata>
    <Item Key="setting.operatingMode">Email</Item>
    <Item Key="setting.showSignupLink">false</Item>
    <Item Key="ContentDefinitionReferenceId">api.selfasserted</Item>
  </Metadata>
  <IncludeInSso>false</IncludeInSso>
