You mean the maximum numbers of parameters to a stored procedure, which is 2100?
You can file a suggestion on https://feedback.azure.com/d365community/forum/04fe6ee0-3b25-ec11-b6e6-000d3a4f0da0. I recommend that you include a strong business case why 2100 is not enough.
But most likely if think you need that many parameters, you are doing something wrong.
