您可以在模块中创建端点：

// fd-route.bicep

param frontDoorName string
param endpointName string
param routeName string

... 
resource frontDoor 'Microsoft.Cdn/profiles@2022-11-01-preview'existing = {
  name: frontDoorName
}

resource endpoint 'Microsoft.Cdn/profiles/afdEndpoints@2022-11-01-preview'existing = {
  parent: frontDoor
  name: endpointName  
}

resource route 'Microsoft.Cdn/profiles/afdEndpoints/routes@2020-09-01' = {
  parent: endpoint
  name: routeName
  ...
}

然后你可以像这样从你的主

param isFdEndpointExisting bool
param fdProfileName string
param fdEndpointName string
param routeName string 

...

// Get a ference to front door
resource fdProfile 'Microsoft.Cdn/profiles@2020-09-01' existing = {
  name: fdProfileName
}

// Create the endpoit if not exists
resource endpoint 'Microsoft.Cdn/profiles/afdEndpoints@2020-09-01' =if(!isFdEndpointExisting) {
  parent: fdProfile
  name: fdEndpointName  
  ...  
}

// Get a reference to the existing endpoint if already exists
resource endpointExisting 'Microsoft.Cdn/profiles/afdEndpoints@2020-09-01'existing =if(isFdEndpointExisting) {
  name: fdEndpointName
  parent: fdProfile
}

// Create the rouyte
module route 'fd-route.bicep' = {
  name: routeName
  params: {
    frontDoorName: fdProfile.name
    endpointName: isFdEndpointExisting ? endpointExisting.name : endpoint.name
    routeName: routeName
    ...
  }
}
