You absolutely can, and the government has, banned exclusive deals and associations before. The government would require that any interactions given between two products Google presently offers as something competitors can replace either side of, with no special advantage permitted to be offered to the formerly Google products, for example.
So, for example, Google could be forbidden from requiring Google product apps are preloaded on Android phones. They could be required to give alternate web browsers and account systems equal visibility in new Chrome installs, for free. Google could face penalties for injecting Google Meet links into Zoom emails received by Gmail users.
The ways the government could prevent Google's self-preferencing is a very large matrix.
Apple has some similar examples, though less. I think Epic v. Apple will accomplish some big things there, particularly around the App Store.
