So when we define the function, we MUST specify the array size 
to be able to accept a static array?
Can't we just define a function which can accept any static 
array with any size? (e.g. a function to calculate average of a 
static int array of any size)?

Static array can be accepted in place of dynamic:

        void foo()
        {
                int[3] arr = [1, 2, 3];
                
                bar(arr);
        }
        
        void bar(scope int[] arr)
        {
                import std.stdio : writeln;
                writeln(arr); // [1, 2, 3]
        }

But be careful not to escape such variables. Demonstration:
