When you try to load a kernel extension in macOS Big Sur b7, kextload gives you the silent treatment:

it does not load the kernel extension.
it does not print any error.

Using kmutil directly does not solve the issue.

Using the --verbose option of kmutil does not print anything.

kextstat shows only Apple kernel extensions.

I have trouble with Symantec (SEP) extensions every time I install a new update. Running the kmutil command from Recovery mode triggers panic medic after I reboot and it disables the problematic extensions so that I can actually finish booting without a kernel panic.
