Is it possible to customizing the controls ? in EFL ? not EDJ or UIBuilder.
Priority for UIBuilder actually

In the below picture the spinner controls has top and down arrows to increase or decrease the number, or Date and year. Can we hide them or change their color ? And change the behaviour after clicking the up and down arrow buttons ?

Similarly for the calender control.
