How to stop autocomplete of form in VBCS?

Summary:

I have a single select required field which is getting auto populated by saved data on the browser with incorrect value. If the required field is populated a button is enabled. The user feels that he has entered the required value but the still the button is disabled. How do i stop autocomplete of form data or how do i validate it if it is populated by the form data? Since it is invalid data it doesn't store the value in the single select variable as well.
