Try increasing the roughness in the base material node (and decoration node if present). This works for me with the free version.

Dear @B1Trash!
I tried but I cannot find where to change the roughness?
Could you help me the path or roughness edit, for example:
Node Decoration/mb_base_decoration/...
Thanks a lot and waiting for your reply.

In the example below, the base color of the part is black and there is a green print on the top and bottom of the parts. There is a reflection that spans all three of the 1x1 bricks. I turned up the roughness for the middle part to 0.5 for both the decoration and the base material. To get to this option, open a Shader Editor Window and select the part that you want to change. Then adjust the Roughness value(s) to tone down the reflections.

I'm sure there are other ways of doing this, but it works for me.
