I've been working on a rpi 4 version of this. The pi4 supports gadget
mode and host mode simultaneously so I have a HDMI framegrabber (and
VGA->HDMI for the machines that don't support HDMI) along with a 4 way
HDMI kvm switch to allow me to control four machines from a single RPI
(for circa 100GBP).
There are other solutions on the web but all of them use the standard
USB keyboard gadget that doesn't work with every bios that I have so
I've had to build my own.
Let me know if you're interested but it's not quite "production ready"
yet - the electronics to control the power and reset switches and
monitor the power and HDD led are on a breadboard at the moment...
