I believe this is what you wanted. https://docs.microsoft.com/en-us/azure/data-factory/parameterize-linked-services As doc mentioned, UI only supports 8 linked service. For others, you could change json code directly following the same pattern.

{
"name": "AzureBlobStorage12",
"type": "Microsoft.DataFactory/factories/linkedservices",
"properties": {
    "parameters": {
        "accountName": {
            "type": "String"
        },
        "accountKey": {
            "type": "String"
        }
    },
    "annotations": [],
    "type": "AzureBlobStorage",
    "typeProperties": {
        "connectionString": "DefaultEndpointsProtocol=https;AccountName=@{linkedService().accountName};AccountKey=@{linkedService().accountKey};EndpointSuffix=core.windows.net;"
    }
}

}

You can't put the entire connection string as an expression. You need parameterize every part separately. Make sure you noticed the prameters field. And then every time you use the linked service, you will be able to pass different values to it.
