If you use berrybrew, you need not do anything at all with your existing install.

• Install berrybrew via its installer. During the install, you can select a version of perl to install with it
• Switch to the new instance: berrybrew switch 5.32.1 (or via the UI)
• Install the bundle

You can also register your existing Perl installation with berrybrew if you desire: berrybrew virtual some_name, then follow the prompts to enter path information.
