Every time I start a print on my Ender 3 v3 KE the check mark to run calibration automatically checks. Is there a way to disable this?
Yes, there is a way.
When you select the file to print, look at the screen. There is a check box that says ‘Calibration’ Uncheck that box 
Also if you edit the starting g-code you should see G29, comment this out or delete, that command tells it to do a mesh levelling.
Is there a way to make it so I don’t need to uncheck it every time?
By editing the start gcode, click on your printer and click manage, you should see gcode under the line G28;home comment out or delete the G29 line, should stop it from bed meshing every print.

If you print from your computer, then editing the gcode works BUT if you select the job from the mini screen on the KE, the calibrate box is always ticked no matter what is in the gcode.
So I would like know, as posted by the original poster, can we turn this off from the small KE screen by editing the firmware?

I have the same problem when printing from Orca, always a calibreation first. The printer start code has G28 and no G29. The only way to print w/o calibration is to uncheck it on the printer screen, every time you start a print. However, I found out that if you manually perform a home on the screen it works without calibrating first. This indicates there’s no load of the mesh at all.
Kind of annoying not being able to print direct from the Orca slicer.

That logic is built into the (closed source) Nebula screen code.
I would recommend you replace the GUI with Guppy Screen.
I can share my STL for mounting the screen in Landscape mode.
Sounds interesting. Do things like the Creality app and Timelapse still work?
Yes. It only replaces the GUI locally on the pad.
How hard would it be to remove if I decided I didn’t like it?
