I have this error in console:

Highcharts warning: Consider including the "accessibility.js" module to make your chart more usable for people with disabilities. Set the "accessibility.enabled" option to false to remove this warning. See https://www.highcharts.com/docs/accessibility/accessibility-module.

Cannot find in documentation where Set the "accessibility.enabled" option to false.

This is the option that I pass to component:

const optionNUsersPerService = {
        chart: {
            plotBackgroundColor: null,
            plotBorderWidth: null,
            plotShadow: false,
            type: 'pie'
        },
        title: {
            text: 'Utenti per servizio'
        },
        tooltip: {
            pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>'
        },
        accessibility: {
            point: {
                valueSuffix: '%'
            }
        },
        plotOptions: {
            pie: {
                allowPointSelect: true,
                cursor: 'pointer',
                dataLabels: {
                    enabled: true,
                    format: '<b>{point.name}</b>: {point.percentage:.1f} %'
                }
            }
        },
        series: [{
            name: 'Utenti',
            colorByPoint: true,
            data: getDataUsersPerService(props.items)
        }]
    }

And this is the component:

return (
        <HighchartsReact
            highcharts={Highcharts}
            options={currentOptions}
            immutable={true}
            callback={props.callback}
        />
    );
