Photoshop autoscroll help

Hi,
Does anyone know how to turn off or atleast extend the boundaries for photoshop to autoscroll the document.

Example. If you select a marquee and head towards the corner, photoshop automatically scrolls the document super fast.

If your drawing a gradient and you move towards any edge of the screen photoshop simply autoscrolls the document if the doc is large.

Any inputs on how to disable or lower the speed?

Many thanks in advance…!!!
