c# - ASP.NET Core : AllowSynchronousIO = true per endpoint vs per server

Question

Im using Net Core 3.1 web api and I need to set AllowSynchronousIO = true. I have seen 2 differents ways to do it:

Per Server (affects all endpoints)

services.Configure<KestrelServerOptions>(options =>
{
     options.AllowSynchronousIO = true;
});

Or per Endpoint (inside a Controller's method):

var syncIOFeature = HttpContext.Features.Get<IHttpBodyControlFeature>();
if (syncIOFeature != null)
{
    syncIOFeature.AllowSynchronousIO = true;
}

Question: if I set AllowSynchronousIO=true per server all my endpoints are Synchronous? Is there a performance issue to set AllowSynchronousIO=true per Server VS per Endpoint? Whitch is better? Or it's just the same.
