Mercedes Sprinter 2012 Tachograph Removal

Hi.

We have a 906 2012 Sprinter with dead tachograph. Tachograph not required in our country, so how can I disable it from KI using DAS?
I tried variant coding in cluster but cant find the option to disable it. Someone done ever this?
Maybe wording in German to disable and it is different from variant coding menu?

Thanks in advance.
