Deactivate alarm system / DWA permanently

Moin, my parents have been proud of Mokka owners since yesterday. This morning the alarm went off for the first time, why is it questionable. (Private property nobody was there). We didn’t know that the car had an alarm system at all. Can you turn it off permanently for inside and outside? So anything to expand, jam it? Please no instruction that an alarm system makes sense. You just don’t want to have it, after which the almost 30 years of Astra has given up the mind, is that simply too much modern technology at once. You are afraid that they will always forget to turn off when the dog sits in it… I am happy about help. Thank you in advance!!!!
