You can do this simply with the delete operator which removes a property from an object. In this case, you can use:

delete regions.regions[0].Shops;

let regions = [

Use delete to get rid of an object, or maybe multiple if you wanted to.

"regions": [
            {
                "Id": 1,
                "code": 1,
                "name": "Trivandrum",
                "Categories": [
                    {
                        "Id": 1,
                        "category_id": 1,
                        "region_id": 1,
                        "ref_count": 2,
                    }
                ],
                "Shops": [
                    {
                        "Id": 33,
                        "is_enabled": true,
                        "is_setup_complete": false,
