This opsmgr agent task allows you to set the secRMM "AllowedSerialNumbers" property. The secRMM AllowedSerialNumbers property tells secRMM which SerialNumber(s) are allowed to be written to. The secRMM AllowedSerialNumbers property can also be used to completely disallow use of Removable Media. This is accomplished by specifying a value that will never match any SerialNumbers within your environment. The value of the secRMM AllowedSerialNumbers property is a semicolon separated list of SerialNumbers.
