Lenovo Asset Tag tips?

I work at an electronics recycling facility. We’ve managed to find a couple tools for clearing Lenovo asset tags, but of the two we have -

First is a DOS tool, manages to clear tags on ThinkStation minis and some Thinkpads, seemingly 7th gen and prior with

cctk --Asset= 

as well as

cctk --propowntag= 

(a space following both commands after “=”)

The second works exclusively on the minis. I’ve read that Lenovo uses AMI bios for some machines, hence our command

amideefix64 /ca ""

Both of those tools were found before I took the helm looking for answers.

First question - is there a current tool for removing Thinkpad Asset tags?

Second (and third) - Anybody have suggestions for making a mostly all-in-one tool? Does one exist already?

TIA!
