   That doesn’t sound right to me. /etc/fstab is interpreted by a userland   
   process (/sbin/init). That only starts running after the kernel has been   
   booted. So mounting the boot partition at this point will make no   
   difference to your running kernel. (Presumably /boot/firmware might   
   contain firmware relevant to connected hardware and its drivers, but   
   that’s a separate issue.)   
      
   (Not a Raspberry Pi user, but this should be basic Linux stuff common to   
   all architectures.)
