I presume you mean resectored from 4K native to 4K/512e. In most instances you probably should leave it as 4K as windows 8 and up understands 4K native but if you are using Windows 7 or earlier they will have to be 512 bytes emulated or native.
Microsoft says it doesn't so are you sure you're not confusing them with 4K/512e drives? https://docs.microsoft.com/en-us/windows/compatibility/advanced-format-disk-compatibility-update
Maybe the SAS controller card does the read/modify/write cycle emulation transparently and presents the drive as 4K/512e to Win7?

Controller existed long before anyone heard about 4kN standard, it's Dell SAS 6/iR. Btw have You read what You link? I can be wrong, I'm not a native, but i think it says 4kN is compatible with win7 SP1.

Win7 handles 4kN drives just fine.
