How to hide radio button circle using custom css on a specific question?

Use the below code:
jQuery("#"+this.questionId+" .q-radio").css("visibility","hidden");

rondev Thank you so much that helped. But when i click on the labels it doesn't show as its selected. How can we make it look like selected?

Thank you rondev. Changing the layout would change all the questions layout to classic. I wanted this functionality only one question.

salma2019 Which theme are you using? It would be easier if you shared a preview link to the question block.
