Azure Frontdoor Apex domain reference

[aslan-im]

Bicep version
Bicep CLI version 0.30.23 (ec3612efc7)

Describe the bug
As far as I know it is impossible to add apex domain to the frontdoor via bicep. But it is possible to add them manually. Earlier if the domain was somedomain.com, the resource name was somedomain-com. I noticed that Microsoft changed this behaviour and adds some random string to the name like this: somedomain-com-ad5e
Is there any way to refer to the manually added apex domain without hardcoding the name with suffix?

To Reproduce

1. Create Azure Frontdoor
2. Add apex domain to the custom domains
3. Try to refer to apex domain by its name like in this example

resource CDN 'Microsoft.Cdn/profiles@2022-11-01-preview' existing = {
  name: profileName

  resource customDomain 'customDomains' = {
    name: replace(zone, '.', '-')
    properties: {
      hostName: zone
      tlsSettings: {
        certificateType: 'ManagedCertificate'
        minimumTlsVersion: 'TLS12'
      }
      azureDnsZone: {
        id: DNS.id //<-- based on th docs you might want to add this value as well.
      }
    }
  }
}

Additional context
I need to associate rules with this domain using bicep
