vue – reference values in setup() function in html template

I am trying to setup the demo code that comes with “vee-validate” (https://vee-validate.logaretm.com/v4/examples/multistep-form-wizard)

I have some fields on the inital form page that if contain a certain value, i want to hide and show certain elements using “v-if=”true/false”.

Normally i reference a variable stored in the “data()” part of the vue file to toggle show/hide but i cannot find a way to pass a value i obtain/set in the “setup()” function of the vue project. It also will not allow me to set values in “data()” by doing “this.variable = true” like i can normally do in a function.
