Featured Image help

Hello

https://opinionesabiertas.com/

I have created a post with a featured image (which displays ok on the homepage) However, I also add the same image, but larger in the post also.

In the post, both the smaller images from the ‘featured image’ and the larger one shows at the same time

My question is Can I set the featured image to show on the home page only and not within the post page?

Thanks
