List of printers limited by number of printers page by 100!

Getting list of universal printers from Azure by next code:

            var queryOptions = new List<QueryOption>
            {
                new QueryOption("$top", "300")
            };

            var printerItems = await ApplicationGraphClient.Print.Printers
                .Request(queryOptions)
                .Filter(filter)
                .Select(x => new
                {
                    x.Id,
                    x.DisplayName
                })
                .GetAsync();

If I increase above 100 like 300 - it still returns 100 items.

Is this hardcoded for UP API?

If I use 10 - it works - so code is valid.

P.S. I know I can use pagination but I'm interested to increase the page size
