A31030 Module

Hi, I have the Neje 3 pro with the A31030 adjustable focus, my question is, can I set the laser dot at about 40mm and then use the adjustment plate of the module to move up and down rather than moving the focus adjuster, I find it hard to find the dot with this adjuster as I see a lot of other light around the dot.

Put a piece of paper like this on the bottom
