How to configure KeepAliveInterval HubOptions for Azure SignalR Service?

Is there a way to configure the KeepAliveInterval option for a SignalR hub when using Azure SignalR Service?

I’m primarily a frontend developer, so I’m not very familiar with the backend setup. We are using Azure SignalR Service with a ServerlessHub in an in-process model, as far as I understand. You can see the relevant documentation

I’ve gone through the available docs but haven’t found a way to configure this option. A backend developer mentioned that it should be added to our local.settings.json. Currently, our configuration looks something like this:

{
  "values": {
     "Azure:SignalR:HubProtocol:NewtonsoftJson:CamelCase": true,
   }
}

Any help or guidance would be appreciated!

Thanks!
