Lightbox - deactivate underlying components?

Hello

I have a desktop design with many components that have hover and click actions on them. If I now open a lightbox then the entire viewport is covered with a 90% color. In the center there is a dialog. So far so known. But in the preview the user can still reach the components under the lightbox and the hover effects are visible. What should not be. How can I block this?

Thank you in advance!
