USB 3.0 KVM Switch HDMI 4 Computer 1 Monitor 4K 60Hz SPDIF L/R Hotkey - Share one Set of Keyboard Mouse Printer,1080p 120Hz 144Hz HDCP Bypass,4X USB3.0 Cable,IR Remote Ext. Windows Mac 41KVMP

I got previous version of this one. (Yeah its a bit pricey) https://a.co/d/0fXeDDTu I was originally using this with a BliKVM board on a pi 4. Then repurposed the pi for something else and bought the Glinet comet. Also I think any cheaper KVM switch that allows input switching via hotkeys/keyboard combos should work.
