Flatpickr setting disabled dates using an array and days of week setting

Question

I am trying to set up flatpickr to disable certain dates based on a csv file AND disable certain days of the week. I am not able to get both working at the same time, only one or the other.

My code so far:

$(document).ready(function () {
var csvurl = "dates.csv";
$.ajax({
    type: "GET",
    async: false,
    url: csvurl,
    dataType: "text",
    success: function (data) {
        var csvArray = $.csv.toArrays(data);
        fCsvArray(csvArray);
    }
});
function fCsvArray(csvArray) {
    var daysArray = [];
    for (var i = 0; i < csvArray.length; i++) {
        var newItem = csvArray[i];
        daysArray.push(csvArray[i][0]);
    }
    console.log("daysArray = " + daysArray);
    flatpickr.localize(flatpickr.l10ns.ja);
    $("#nkibo-date1").flatpickr({
        disable: [
            function (date) {
                return (date.getDay() === 0 || date.getDay() === 1 || date.getDay() === 2 || date.getDay() === 6);
            }
        ],
        //disable: daysArray,
        locale: {
            firstDayOfWeek: 1
        },
        disableMobile: true,
        minDate: new Date().fp_incr(7),
        dateFormat: "Y/m/d"
    });
}

});

If I comment out the first "disable" function and run the script with the second "disable" code, that part works too but I would like them to work together. I have read that using the Enable and Disable options together is not possible, since I tried to enable the days that are available, then adding the Disabled dates afterwards, as a workaround.

The dates are as follows (in case anyone needs them):

2022/10/06
2022/10/07
2022/10/12
2022/11/23
2022/12/07
2022/12/08
