Making a bone hides using a switch?

Question

Is it possible to make certain bone disappears/switch looks, using a switch or some sort? I had this assumption after seeing auto rig pro's rig ,where if i switch fk to ik , vice versa, i see the bone changes shape. Thank you.

There's multiple ways to make an FK/IK Switch in Blender. Here's the blend file of the method I use :

And here are the steps I go through to make it :

• Create a separate bone, visible at all times
• Add a custom property on this bone
  • Type : Integer
  • Name : "FK/IK Switch"
  • Default : 0
  • Min : 0
  • Max : 1
• Right-click on the custom property > Copy as New Driver
• In the outliner, paste the driver onto the visibility switch of the desired bones :

• Change the expression on the FK bones to 1 - custom_property
• Done !
