Code-switching is the way people act differently in different contexts. So you're more likely to be formal and polite with your boss or grandparents and around your friend group you'll be more casual, maybe swear more.
Code switching originally was a term in linguistics to refer to the same speakers using multiple languages (or multiple registers of the same language, etc.) in a single conversation, which is probably why imbnwa is confused about the application here. In the last few years it's been picked up by the broader social science world to describe people using different modes of speech in different situations, which is how you're using the term--e.g., using a "white" voice, using a "straight" voice, etc.
You can call it disingenuous if you want, but it's just the reality that different behavior is appropriate in different contexts, and different relationships have different expectations.
