How to deactivate Trados 2021 on one computer only (Freelance Plus edition)

Hi! Can anyone point me to information on how to deactivate Trados 2021 on only one of the two computers I have? I'm getting a new laptop this week, and would like to uninstall and deactivate Trados from one of the two laptops I own, so I can install Trados 2021 on the new computer. I have Trados Freelance Plus. 

Thank you!
