Enabling silent mode on the supermicro sys-6019p-mt server?

Question

Supermicro

Good day, please tell me how to enable silent mode in the fan settings on the supermicro sys-6019p-mt server (there is no such mode in the options, there is: set fan to standard speed, set fan to full speed, set fan to optimal speed, set fan to heavy io speed). On older servers, there was a silent mode.

There are 6 turbines in a row, which must suck air through the body. It cannot be quiet.
