Modifications in upload car form

Hi, nice to talk with you!

1. I would like to know in which section of the theme I can modify and reduce the number of years shown in the form to load cars? Attached screenshot, I would like it to be from 2021 to 2010
2. I would like to know if in the form to load a car, you can create a radio field that displays many options with different locations?
3. In the guarantee field, I would like that when the user clicks YES, a new field is displayed where the value of said guarantee is inserted. Can this be done? Thank you!
