@IvanNosatlev  On Dell systems, CSM is called Legacy Option ROMs. But as mentioned above, installing Windows 7 might not be feasible for other reasons. I’d strongly suggest that you install it as a VM instead. You will avoid driver issues and will be able to keep your main system running a modern OS that is still receiving security updates.

The last systems with Windows 7 support were designed in 2015.  Anything newer is Windows 10 only.

And most systems from the last 2-3 years have no legacy support - they are UEFI only.

We can't answer definitively without knowing exactly which system you have, but those points should help you ascertain whether or not what you have will support what you want to do.
