       Change  the  value  of  one  or  more boot configuration settings. To reset the value of a setting to its
       default, simply omit the new value.

       pibootctl-set - pibootctl manual

name=[value]
              Specify one or more settings to change on the command line; to reset a setting to its default omit
              the value.

       -h,--help
              Show a brief help page for the command.

       --no-backup
              Don't take an automatic backup of the current boot configuration if one doesn't exist.

       --all  Set the specified settings on all Pis this SD card is used with. This is the default context.

       --this-model
              Set the specified settings for this model of Pi only.

       --this-serial
              Set the specified settings for this Pi's serial number only.

       --json Use JSON as the input format.

       --yaml Use YAML as the input format.

       --shell
              Use a var=value input format suitable for the shell.

          pibootctl set [-h] [--no-backup] [--all | --this-model | --this-serial]
                        [--json] [--yaml] [--shell]
                        [name=[value] [name=[value] ...]]

       The set command can be used at the command line to update the boot configuration:

          $ sudo pibootctl set video.overscan.enabled=off
          Backed up current configuration in backup-20200309-230959

       Note that, if no backup of the current boot configuration exists, a backup is automatically taken (unless
       --no-backup is specified). Multiple settings can be changed at once, and settings can be reset  to  their
       default value by omitting the new value after the "=" sign:

          $ sudo pibootctl set --no-backup serial.enabled=on serial.uart=

       By  default,  settings  are  written  into  an "[all]" section in config.txt meaning that they will apply
       everywhere the SD card is moved. However, you can opt to make settings specific to the current  model  of
       Pi, or even the current Pi's serial number:

          $ sudo pibootctl set --this-serial camera.enabled=on gpu.mem=128

       In  this  case  an  appropriate section like "[0x123456789]" will be added and the settings written under
       there.

       For those wishing to build an interface on top of pibootctl, JSON, YAML, and shell-friendly  formats  can
       also be used to feed new values to the set command:

          $ cat << EOF | sudo pibootctl set --json --no-backup
          {"serial.enabled": true, "serial.uart": null}
          EOF
