Hi there, I found some threads that I think might help get you started. I also put their solutions into a QSF for you to reference, and am including the code below as well.
One option is use 2 questions to implement - 1 that is a Text/Graphic and just displays information to the respondent (to display labels), and the 2nd question is the clickable question which is entirely hidden until 2 seconds after page load. The code to delay the appearance of an entire survey question is below:
Qualtrics.SurveyEngine.addOnload(function()
{
    this.getQuestionContainer().hide();


});


Qualtrics.SurveyEngine.addOnReady(function()
{
    var delayTime = 2000 //This is the time of delay
    var that = this;
    setTimeout(function(){that.getQuestionContainer().show()}, delayTime);  


});

A 2nd option is a little closer to what you initially described. It includes a delay for displaying the buttons but I wasn't sure how to make them not clickable. It uses a matrix question and the below code to delay the appearance of the radio buttons:
Qualtrics.SurveyEngine.addOnload(function()
{
    this.getQuestionContainer().querySelectorAll("eclass^='q-']").forEach(button => button.hide());


});


Qualtrics.SurveyEngine.addOnReady(function()
{
    var delayTime = 2000 //This is the time of delay
    var that = this;
    setTimeout(function(){that.getQuestionContainer().querySelectorAll("qclass^='q-']").forEach(button => button.show())}, delayTime);  


});
