Possible to null / clear a property using the powershell module?

I'm trying to clear some values on a person entity but I'm getting errors like the below:

get-person -DefaultEmailAddress [email] | Set-Person -CustomProperty01 $null
Resolve-Exception : Cannot validate argument on parameter 'Value'. The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.
The argument is null or empty. Provide an argument that is not null or empty, and then try the command again.
