Hi, I own Dell XPS 9570 with 8th-gen Intel Core i7-8750H CPU. Is it safe to turn off speed step, turbo boost and C states?

Hello DToja,

Thank you for posting on the Intel communities. 

Disabling these features/technologies should not affect the functionality of the system and should be safe. Nevertheless, I would strongly recommend to ask the same question directly to Dell* so they can confirm this since they are the ones who assembled the system you currently use.

I hope this helps.
