Stop this idiocy.
The above has now been answered multiple times, several different ways.
The "point" of secure boot may be that you had no choice, or there was
no point at all, it just came that way.
Or the "point" of secure boot may be that you don't trust anybody else
than yourself, but once you've booted you do trust what you booted.
But the *real* point is that this has nothing what-so-ever to do with
secure boot. You may want (or not want) lockdown independently of it.
Don't tie magic boot issues with kernel runtime behavior.
