Turning off Apple hardware checks on startup

You can’t bypass this.

It’s technically not an Apple limitation as all computers (PCs too) need to run a minimal set of tests to probe how much RAM is available, what boot devices are present, etc. Without it, your Mac wouldn’t know from where to boot from at a very minimum

There is no official way to disable hardware checks when your Mac boots up.

These hardware tests are collectively referred to as the Power On Self-Test (POST) stage. These checks are considered critical to safely and securely booting the operating system.
