If you’re not doing this as a hack but to get more control over your own processor, you can just turn off secure boot, it’s a bios setting.

  Sure. But preferably install your own keys and sign bootloader and operating system yourself if you run untrusted code on the machine.

    You can't install your own microcode signing key. Only intel's is provided, and it's in unmodifiable mask ROM.
