Options GRUB_HIDDEN_TIMEOUT and GRUB_HIDDEN_TIMEOUT_QUIET are deprecated in grub. Use

info -f grub -n 'Simple configuration'

and then you read in there:

`GRUB_HIDDEN_TIMEOUT'
     Wait this many seconds before displaying the menu. If <ESC> is
     pressed during that time, display the menu and wait for input
     according to `GRUB_TIMEOUT'. If a hotkey associated with a menu
     entry is pressed, boot the associated menu entry immediately. If
     the timeout expires before either of these happens, display the
     menu for the number of seconds specified in `GRUB_TIMEOUT' before
     booting the default entry.

     If you set `GRUB_HIDDEN_TIMEOUT', you should also set
     `GRUB_TIMEOUT=0' so that the menu is not displayed at all unless
     <ESC> is pressed.

     This option is unset by default, and is deprecated in favour of
     the less confusing `GRUB_TIMEOUT_STYLE=countdown' or
     `GRUB_TIMEOUT_STYLE=hidden'.

`GRUB_HIDDEN_TIMEOUT_QUIET'
     In conjunction with `GRUB_HIDDEN_TIMEOUT', set this to `true' to
     suppress the verbose countdown while waiting for a key to be
     pressed before displaying the menu.

     This option is unset by default, and is deprecated in favour of
     the less confusing `GRUB_TIMEOUT_STYLE=countdown'.
