It does, the hardware owner merely has to tell macOS what it wants. Open a Terminal and type:

    sudo spctl —-master-disable

And you’ll be able to run as many unnotarized apps as you wish, just by double clicking them.

However, if the hardware owner wants to disallow unnotarized software, macOS should enforce that policy.

No, you’re thinking of csrutil --disable for turning off System Integrity Protection. You don’t have to do that to run unnotarized apps.
