The same way TOR does it - by not recognizing a female Revan.
If you choose a female Revan, even if you did everything exactly canonical you can assume the result of your ROR playthrough will not lead up to the events of TOR as Satele Shan couldn't possibly have been born. To reach the events of TOR, you'd have to play ROR in a very particular way to get to those chain of events.
Of course, strictly following the canon path is not what we recommend players do. Different play styles and choices will result in radically different outcomes, Revan's gender and alignment is one of them. We'd want players to freely choose their options just like you would in Kotor I and Kotor II and we want players to replay the ROR mod to explore different scenarios.
