Actually, using a page builder like WPBakery will make a big difference. conditionally showing a value based on another value will require custom php code or some type of coding option or conditional templating tags provided by the builder. I cannot give you any information on how to use your page builder, for that you would need to contact support for that page builder of find a user forum where you can ask for help with the page builder.
Using PHP code would look something like this
if (get_field('not_this_field') == 'some_value') {
the_field('this_field');
}
