Install the Stylus Chrome Extension then add this UserStyle to the extension. You will then reveal these hidden settings in /cgi-bin/minerConfiguration.cgi, such as

But all matter is the control of the voltage! so where is it?

Just curious - What does "Beeper Ringing" do?

I think you don't need to download the stylus chrome extension to reveal the hidden features you can do it manually by following this guide https://bitcointalk.org/index.php?topic=2690140.0

There's no voltage control if you do this method I think you can try to check this thread https://bitcointalk.org/index.php?topic=4425212.0 and edit the set_miner_conf.cgi find the line with voltage then you can edit the value whatever you like.

Just curious - What does "Beeper Ringing" do?

According to some article about antminer s7 it's a beep sound so if you uncheck the "beeper ringing" it might remove the beep sound of the miner.

Older models such as the S7 and earlier had a beeper/buzzer that would sound when there was a fatal error. You could disable the beeper using that menu option.

It is irrelevant with the S9 since it has no buzzer. On the S9, fatal errors are only shown by the red blinking light.
