Hello SShinde-4528,
Thank you for your question.
Most of the features present within windows 10 will be present in windows 11, but with some subtle changes in design and performance.
About the surface book 2 drivers you can check how to download them manually or automatically in the article below:

In addition, you can follow the changes within windows 11 in the windows 11 forum itself, there I think it will be more useful for you to discover the features that are still present or not:
