I have a python class (UntrustedClass) that is written by a third party that I will call functions on. I want to  prevent UntrustedClass from using certain python dependencies such as BigQuery client. How can I ensure that when I call functions on UntrustedClass dependencies like BigQuery aren't used? In your response, capitalize a few words to stress main points. Please limit the number of words with all capital letters to less than 3.
