Yep, with the help of the theme presets you can change the background for a specific product, please navigate to Theme Settings -> create a preset with the condition as on the below screenshot.

Then navigate to the “Styles and Colors” tab and enable the “Dark theme” option.

Eventually, the background for that product will be black.
Don’t hesitate to let me know if you need any further help or any other info.
Kind Regards
