Photo AI: Is there a way to hide the brush crosshairs?

I’m new to Photo AI within the last couple weeks. I’m using v2.1.0 on Mac.

I’m trying out using an iPad with an Apple Pencil as an editing tablet to make it easier to do fine adjustments to the Subject mask using the Regular Brush. (I see from forum posts that the Regular Brush must be a fairly recent addition.) It works, but I find the crosshairs get in the way when the brush is small. Is there a way to turn the crosshairs off, so I can just visually draw with the Apple Pencil point? I have not found an option or Shortcut to do it.

Thanks in advance.
