PiKVM (https://pikvm.org/) is a very powerful and Open Source Software which allows for a remote connection via your Raspberry Pi to turn on/off or restart your computer, configure the UEFI/BIOS, and even reinstall the OS using the Virtual CD-ROM or Flash Drive. You can use your remote keyboard and mouse or PiKVM can simulate a keyboard, mouse, and a monitor, which are then presented in a web browser as if you were working on a remote system directly. It's true hardware-level access with no dependency on any remote ports, protocols or services!
