The short answer is No. There is no Universal or Common-practice Command for this.
But the longer answer is probably Yes. Manufacturers often use a Non-public Command in the range 122 to 126, to write either specific information, or as a general *write to memory location* function. A user is not expected to know or use these commands, and for safety they may demand a password.
