Whether to enable LACT, a tool for monitoring, configuring and overclocking GPUs.
::: {.note}
If you are on an AMD GPU, it is recommended to enable overdrive mode by using
`hardware.amdgpu.overdrive.enable = true;` in your configuration.
See [LACT wiki](https://github.com/ilya-zlobintsev/LACT/wiki/Overclocking-(AMD)) for more information.

Settings for LACT.
The easiest method of acquiring the settings is to delete
{file}`/etc/lact/config.yaml`, enter your settings and look
at the file.
::: {.note}
When `settings` is populated, the config file will be a symbolic link
and thus LACT daemon will not be able to modify it through the GUI.
