Request assistance granting user permission to execute a sys function from within a package

I'm trying to grant a user execute permissions to SYS.DBMS_UTILITY.GET_PARAMETER_VALUE so I do not need to grant select on the V$ views.

I can grant it on the package DBMS_UTILITY but not the specific function GET_PARAMETER_VALUE:

SQL> grant execute on SYS.DBMS_UTILITY to TEST;

Grant succeeded.

SQL> grant execute on SYS.DBMS_UTILITY.GET_PARAMETER_VALUE to TEST;
grant execute on SYS.DBMS_UTILITY.GET_PARAMETER_VALUE to TEST

I'm using Oracle 12c and this is in a pluggable database.
