How to disable element when site is viewed by a robot?

Hi everyone,

I’m currently building a site using Bricks & Bricksforge. On my landing page, I’m using the Bricksforge functionality “3D Model” to load a background model.

The model is pretty lightweight and loads decently even when opening the site on an old computer. However, most of the “site health” tools, like Lighthouse or GTmetrix, give my site a really bad performance review because the 3D model keeps using a thread to render the model.

So, my question is: Is there a way to disable some elements when the site is opened by a robot, metrics tool, or for indexing?
If I were to implement such a feature myself, where would I start? (I’m an experienced PHP/Web dev, but new to WordPress.)
