Use radio input instead of checkbox on Select Category - Wordpress

I'm currently developing a site for a Church and using wordpress. This Church is an international organization, and have several communities around Argentina and Uruguay. I created a custom post type Community so the users can add a new community or add/modify info related like location (maps) managers, activities. Those communities are related to the wordpress categories with

'taxonomies' => array( 'category' )

My concern is, how I can modify just for the Community Post form, to instead of having a checkbox widget to select the categories, another component to be use, at least change the checkbox to a radio because I want to remove the option to select more than 1 category per Community.
