how to enable ssd emulation

[greenhill]

Hello, I noticed an option to enable ssd emulation. Im trying to enable it on an existing VM but the option is greyed out. Is it possible to enable ssd emulation after the machine is created (this vm is already 2years old) ?

The manual states: Note that SSD emulation is not supported on VirtIO Block drives. Maybe you can switch to VirtIO SCSIi?
