Yes you can use both but I’ve seen some front end developers blank out alt altogether when they are using figcaption.

I did not find this practice in MDN Web Docs but I found it in an other place:

If you’re using an image that has a caption, it may not need alt text if the caption contains all of the relevant visual information.

This doesn’t have to do with figcaption but a blind user in Stack Overflow suggested you should empty out alt for actionable objects.

If you can interact with the image to perform actions (click, etc.), or if the icon conveys an information, then you must set a non-empty alt. It must be a function description, not a objective description of the image.
Example 1: “Go back” is good, while “Blue left arrow” is bad.

I was just wondering what Mozilla’s method was for finding these images and if they took other things in to consideration like decorative images.
