Help with border brush config

[Bruno5D5E]

Hello guys, i'm using hard round with these color but when them overlap the blend transition between them shows very evident.

I want to remove this, want the brush Fully hard, with no transition or any kind of blend in the edge pixels.

Is that possible? Can anyone help me?

How do i config this?

Photoshop seems to use anti-aliasing on brush stroke edges I do not know if that can be turned off. What you see seems to be anti-aliasing blending.

setting brush spacing to 1%  makes the edges more crisp
