Write Caching Windows Server 2019

Hello,

I have a Dell R630 server with H730 raid card with which I made a raid 1 with two 480 GB SSDs.

In the controller I have set:
Default Write Cache Policy: Write Back
Read Cache Policy: Read Ahead
Disk Cache: Enable

When I try to tick in Windows "Enable write caching on the device" I get an error.

Can you tell me what I am doing wrong?
