I have my Windows 10 desktop computer connected to two displays through HDMI – one monitor and one TV, which I can toggle through with Windows Key+P as described in the accepted answer to this question.
However, I was wondering if there was some hotkey, shortcut, or button combination I could use sort of like a "Virtual KVM Switch" that lets me select one display or another specifically, without needing to cycle/toggle through other displays.

The built-in DisplaySwitch.exe tool can emulate the + P capabilities. You can potentially create four desktop shortcuts so that you have one available for each option:
For the PC screen only:
%windir%\System32\DisplaySwitch.exe /internal
For Duplicate:
%windir%\System32\DisplaySwitch.exe /clone
For Extend:
%windir%\System32\DisplaySwitch.exe /extend
For Second screen only:
%windir%\System32\DisplaySwitch.exe /external
