is there any way to change code background color in VScode?

I would like to change the color of the comments so that it can be highlighted. I prefer to change background-color for most of the time. I found the color setting in setting.json. it looks like this.

"editor.tokenColorCustomizations": {
    "textMateRules": [
        {
            "scope": "comment",
            "settings": {
                "fontStyle": "bold",
                "foreground": "#FFD83B"
            }
        }
    ]
}

it does change but it seems like there is no "background" option in "settings". it says "Token background colors are currently not supported." so I only can change the text color, not the background. is there any way I can set background color in VSCode?
