Sure, I could use remote control, but I've found that screen sharing apps eat a little bit of hashing power when you're connected.
I was surprised at how much of a hit to hashrate teamviewer causes, even on a Ryzen 5 1600, and a KVM switch isn't a good choice for me at the moment because the Onda 6-GPU boards have a VGA port while everything else I have shanghaied into mining uses DVI/HDMI/DP (though I guess I could get a bunch of DVI to VGA converter plugs).
