Which kind of kernal function is applied when I run kernel density estimation in ArcGIS PRO?

Question

In QGIS, I can set the function I would use in advance, but it doesn't seem same in here.

I looked all the input option very carefully including 'enviornment setting' tab, but couldn't find anything regarding it. So I thought there is some fixed mechanism when I run KDE. But if so, which one(triangular, quadratic, gaussian...)? I searched very hard...but there weren't any information.

To conclude it, can I set certain kernel function when estimating kernel density? If so, which option do I have to set?

And if I cannot, which kernel function is applied to mimic the outline of histogram of the data that I input in ArcGIS PRO?

So the conclusion is, ArcGIS PRO still uses quartic kernel function to draw the kernel density, and this is fixed so that I cannot change the kernel function without extra coding procedure?

According to the help page How Kernel Density works the kernel function is based on the quartic kernel function described in Silverman (1986, p. 76, equation 4.5).  The formulas are included in that help page.
