How to change the mouse wheel settings in the AutoCAD?

In the screenshot below, in the ArcGIS, the mouse wheel movement (backward/forward) can set to be “zoom in/out” depending on our choice.

Is there such settings in the AutoCAD? How to decide to the backward/forward of the mouse wheel mean?

Thank you for the help,

Best

ZOOMWHEEL system variable.

The ZOOMWHEEL system variable toggles the direction of transparent zoom operations when you scroll the middle mouse wheel.

0	Moves wheel forward zooms in; moving wheel backwards zooms out.
1	Move wheel forward zooms out; moving wheel backwards zooms in.

We might as well mention ZOOMFACTOR variable, probably the next screenshot  look it up in HELP if you get stuck.
