vconsole.conf — Configuration file for the virtual console
/etc/vconsole.conf
The /etc/vconsole.conf file configures
    the virtual console, i.e. keyboard mapping and console font. It is
    applied at boot by udev using 90-vconsole.rules file.
    You can safely mask this file if you want to avoid this kind of initialization.
    
The format of vconsole.conf is a newline-separated list of environment-like
    shell-compatible variable assignments, ignoring comments and empty lines. It is possible to source the
    configuration from shell scripts, however, beyond mere variable assignments no shell features are
    supported, allowing applications to read the file without implementing a shell compatible execution
    engine. See
    os-release(5) for a
    detailed description of the format.
Note that the kernel command line options
    vconsole.keymap=,
    vconsole.keymap_toggle=,
    vconsole.font=,
    vconsole.font_map=,
    vconsole.font_unimap= may be used
    to override the console settings at boot.
Depending on the operating system other configuration files might be checked for configuration of the virtual console as well, however only as fallback.
/etc/vconsole.conf is usually created and updated
    using
    systemd-localed.service(8).
    localectl(1)
    may be used to instruct systemd-localed.service to
    query or update configuration.
The following options are understood:
KEYMAP=, KEYMAP_TOGGLE=¶Configures the key mapping table for the keyboard.  KEYMAP=
        defaults to "us" if not set. Specially, if "@kernel"
        is specified, no keymap will be loaded, i.e. the kernel's default keymap is used.  The
        KEYMAP_TOGGLE= can be used to configure a second toggle keymap and is by default
        unset.
FONT=, FONT_MAP=, FONT_UNIMAP=¶Configures the console font, the console map and the unicode font map.
A few configuration parameters from vconsole.conf may be overridden
    on the kernel command line:
