Hi,
Yes, Efuse partition protection is applied, that makes it impossible to modify the raw data partitions, only the EXT4 partitions (system, cache, userdata) can be modified. Since Android 5.1 only systemless root can work, so that's not possible to root your phone if the boot partition cannot be modified. On Efuse protected devices non-certified (modified) boot or recovery images cannot be flashed.
However, the S2 is not a UMI OS device (no Efuse protection), so you can get root access with Magisk Manager, or you can use the CWM recovery + SU installer shared on the page linked by Marcin here some comments ago.
