Hide date beneath Lightningchart ChartXY with tickstrategy AxisXStrategies.DateTime and dateOrigin set

I'm using Lightningchart (v5+) to display a real-time XY chart of an EEG signal. Everything works exactly like I expected, but I can't find a way to hide the date displayed beneath the chart.

const dateOrigin = new Date();
chart.getDefaultAxisX().setTickStrategy(AxisTickStrategies.DateTime, (tickStrategy) => {
    return  tickStrategy
    .setDateOrigin(dateOrigin)
    .setFormattingSecond(
      undefined,
      { hour: 'numeric', minute: 'numeric', second: 'numeric', hour12: false },
      (x) => 'minor'
   )
} )

The data displayed looks something like:

x: 1714734098, // Epoch Timestamp,
y: 0.5 //voltage

I tried using AxisTickStrategies.Time. That one hides the label beneath, but that strategy does not provide the extensive formatting options AxisTickStrategies.DateTime gives me. The X value displays an unformatted Unix timestamp using this strategy, which I don't want.

I have to set some sort of origin to be able to draw properly.

Is there some kind of method / flag or styling option available to hide the date beneath the chart? I can't find anything in the docs.

I'm not allowed to place images here yet (first post) but it's the date that's displayed right under the chart in a seperate label.

    axis.setTickStrategy(AxisTickStrategies.DateTime, ticks => ticks
    .setGreatTickStyle(emptyTick)
)
