Hello,

I'm trying to change the elasticsearch settings yml configuration from [elastic.co](http://elastic.co)  
When I put `http.max_initial_line_length: 32kb`, it says:

```auto
Your changes cannot be applied

I also tried to change it via terraform but it doesn't work either =\>

```auto
│ Failed with: {" *****":{"root_cause":[{"type":"illegal_argument_exception","reason":"persistent setting [http.max_initial_line_length], not dynamically updateable"}],"type":"illegal_argument_exception","reason":"persistent setting [http.max_initial_line_length], not dynamically updateable"},"status":400}

```

Can you tell me how I can increase http.max\_initial\_line\_length?

Thanks 🙂
