Hello @Tristan ,
Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.
That's correct. Turbo boost is enabled by default on the D-series which is not enabled for B-series. To add more, "Turbo Boost" is an internal implementation and is triggered automatically as needed by the underlying host infrastructure and there is no way to control it or monitor it by customer. This is controlled at the Bios level and you do not have any access to this level of hardware.
As far as I know, the processor on the B-series, does not include that technology and It is not something you yourself can enable or disable.
Hope this helps.
