Magetno 2 – Date format does not render correct

It there is any issue with dateformat tag admin form?
I tried so many format but this does not impact on the output. I am getting date in format dd-mm-yyyy but I want format it like mm-dd-yyyy.
Any suggestion how can I set it?

       
            
                string
                Expiry Date
                date
                customer
                
                    mm-dd-yyyy
