Hey Dresse,

I don't think there is a built-in API. This said, you can style it directly.

Add a css class to the serie you need to rotate to be able to target the markers for a specific serie:

//find your serie in your chart, then add a css class to the serie using plotoptions
chart.getSeries(3).getPlotOptions().addExtraAttr("className",new JavaScriptValue("'myexampleclass'"));

Then just use the css transformations (to test with relevant browsers. This works well in chrome on my side).

<style>
    .myexampleclass .highcharts-point {
        transform: rotate(90deg);
        transform-origin: center;
    }
</style>

If that doesn't work for you, you can also have a look at the API for series Symbols: https://api.highcharts.com/highcharts/plotOptions.series.marker.symbol but that's for a complete replacement of the original marker by something else.

Have a look and tell me what you think ;)
