Uninstall virtual appliance from Vcenter

Hello,

I need to uninstall a virtual appliance from mi vcenter server. This virtual appliance is in a VM and i dont wanna delete the VM, i just need to unregsiter the appliance from the Vcenter server. The virtual appliance is the EMC backup and recovery.

I see this KB VMware KB: Uninstalling vSphere Data Protection from vCenter Server

But im not sure if this is that i have to do.

Thanks  !!
