Each version of Windows has increased the interaction between the OS and the BIOS/UEFI.
While it was still in flux with W8, W8.1 and W10 rely heavily on interaction with the BIOS/UEFI
This is such an important thing that the techbench tool asks that you update the BIOS/UEFI prior to doing the update.
At work we now update the BIOS/UEFI on all systems as a part of finishing our repairs.
In short, yes the OS can change things in the BIOS/UEFI.
As an example, setting the Date and Time in W10 can change the time in the BIOS/UEFI
This is not a 100% true statement - as this hasn't been universally adopted by all manufacturer's
