Before I get started, I do not own the Blender Advanced plugin... so if you have it, this may or may not work for you.

I am using Blender 2.93.4 and Mecabricks Lite 3.1.4 (plugin version can be found in Preferences -> Add-ons, then hit the triangle next to the Plug-in name)

If you use the Blender Lite plugin, there is a way to get decorations to work with Eevee, which also runs Material Preview in the Viewport Shading options. Be aware that this will remove Normal information, which means that stickers and prints will not have a different surface finish from the plastic. This workaround is especially useful if you use Material Preview to block out animations and then render in Cycles. If you are doing this, make sure to reverse what you did before you render to get the Normal data back.

1. Import your model into Blender
2. Open a shader editor
3. Click on a decorated part
4. Open the Decoration group (Click on the icon in the upper right corner)
5. Open the mb_base_decoration group
6. Find the mb_decoration_normal group and select it
7. Mute the node using keyboard shortcut [M]

This node should be shared across all of your decorated parts, so this should "fix" your Blender problem for this file. [M] is a toggle shortcut, so you can hit it again to unmute the group. Again, I don't have Blender Advanced, so I don't know its shader structure and therfore I do not know if this will work or not.
