Availability of HttpClientFactory for Azure Functions v2

I want to know if HttpClientFactory or similar is available for Azure Functions v2.

Below is what is recommended, but HttpClientFactory or similar is not shown.

// Create a single, static HttpClient
private static HttpClient httpClient = new HttpClient();

public static async Task Run(string input)
{
    var response = await httpClient.GetAsync("https://example.com");
    // Rest of function
}

Below is a good link but I am not sure if it can be used on production, or

Problem to solve

1 Providing managed HttpClient pool instead of single HttpClient, like HttpClientFactory in ASP.NET CORE 2.2
