My version of this is to use a serial console server for direct access, rather than vga + keyboard. If the kernel is still running fine but network access is down, I have a getty running on the serial port. If the kernel has locked up too, I hit the reset button by sending a 500ms+ serial break (special circuit, highly recommended) and the bios has serial redirect, so I can do stuff like hit del to drop into bios setup or uefi shell at that point.
But I expect you're probably right some or all of the providers we use do have something like that, as I speculated in the previous post. I've just never understood the point of vga-type stuff when bios/uefi serial redirect exists and serial console is more convenient anyway once the kernel has started, so never asked the question.
