Yes, in WaveLab you can hide certain plugins from being shown. You can also create a favorites list.
As you can see in my screen shot, in the Preferences area I have turned off certain plugins. In this screen shot I have disabled some VST2 versions of DMG Audio plugins so that only the VST3 versions appear in my plugins list.
For UAD for example, I’ve turned off all the guitar and bass amp simulations and other stuff I’ll never need in WaveLab to help clean up the list.
