They won't.

By all accounts, Roscosmos is completely corrupt and NASA can't afford to lose Russia as an ISS partner.

You'll note that even though a SpaceX Crew Dragon was also attached to the ISS at the time, it was not used to counteract Nauka's thrust and the only mention of it was that it could be powered up quickly as an escape pod.

Part of that is due to the low lever-arm position of it, but I also believe it was probably never programmed to provide pitch and yaw support, and maybe not even altitude reboost. I am willing to bet that software is being written right now, though.
