plotting – Plot markers For QuantilePlot

I want to change the plot markers of the data points in QuantilePlot. This seems pretty straightforward:

QuantilePlot[
                RandomVariate[NormalDistribution[0, 1], 32], NormalDistribution[mu, sigma],
                ReferenceLineStyle -> Directive[Red, Dashing[{Large}]], PlotMarkers -> {"[EmptyCircle]"}
            ] 

However we can see that we get a “Null” plot marker at either end of the reference line:

Is there a specific command required in QuantilePlot to customise the plot markers for the data points?
