Azure Features - Parallel Execution Limit

Question

Is it possible to limit the maximum number of parallel functions?

I read the documentation and came across this:

When several triggering events occur faster than the single-threaded function runtime can handle them, the runtime can call the function several times in parallel.

If a functional application uses a consumption hosting plan, the functional application can automatically scale. Each instance of a function application, regardless of whether the application is running on the consumption hosting plan or the usual application service hosting plan, can process parallel function calls in parallel using multiple threads.

The maximum number of simultaneous function calls in each instance of the function application depends on the type of trigger used, as well as the resources used by other functions in the function application.

https://docs.microsoft.com/en-gb/azure/azure-functions/functions-reference#parallel-execution

I use a function in terms of application maintenance with an event hub input binding, and I only have one function in a function application. If I cannot limit this, does anyone know what maximum number of simultaneous function calls will be for this kind of installation?
