How to remove the up and down arrows from the ios input box?

as shown below, my input box binds the click event to call up picker. In order to prevent the system virtual keyboard from being set up, I set input to readonly. Although the virtual keyboard will not be set up, the up and down arrows still come out. Do you know any way to prevent it from coming out?

if I am asked to simulate input with other elements or trigger input with other elements, I wonder if there is a more natural and non-invasive way
