If you no longer want to animate or modify deformers, you can hide the deformation controls so that they no longer clutter the Camera view.
Click in the negative space of the Camera view, Timeline view or Node view to discard the current selection, then click on the Show Selected Deformation Chain and Hide All Others button in the Deformation toolbar.
Select a layer that is not linked to any deformer, then click the Show the Selected Deformation Chain and Hide All Others button in the deformation toolbar.
In the Camera toolbar, click the Hide All Controls button.
From the top menu, select View > Hide All Controls.
