Is there any way to fix sections in the Customizer?

Hello,

I wanted to know if theres a way to prevent sections from being moved in the Customizer when working with Json templates. Is there a way to make the fixed so that they remain in place? I attached a screenshot below to further clarify my issue.

Thank you!

  1. Locate the JSON file for the section you want to make fixed. This file typically resides in the sections directory of your theme.

  2. Open the JSON file and find the settings section. Within the settings, you’ll find an attribute called "presets".

  3. Add a new preset entry to the "presets" attribute, specifying the position where you want the section to be fixed. For example:

"presets": {
  "fixed": {
    "position": 1
  }
}

It says “fixed” is not a valid attribute in theme check,

"presets": [
    {
      "name": "Advert Title",
      "fixed": {
        "position": 1
      }
    }
  ]
