Can't seem to set up early AMD microcode loading with GRUB

Hello, I'm trying to troubleshoot some problems that have been happening, and I saw this entry in the wiki regarding early loading of microcode when using GRUB. Apparently, you really just have to install the amd-ucode (in my case, at least) package and grub-mkconfig will early load it. But, the same article has this line:

journalctl -k --grep=microcode

That's supposed to print something like this when early loading is activated:

microcode: microcode updated early to new patch_level=0x0700010f

However, when I run the same command, it gives me this, with no mention of early loading:

microcode: CPU0: patch_level=0x08701021
microcode: CPU1: patch_level=0x08701021
microcode: CPU2: patch_level=0x08701021
microcode: CPU3: patch_level=0x08701021
microcode: CPU4: patch_level=0x08701021
microcode: CPU5: patch_level=0x08701021
microcode: CPU6: patch_level=0x08701021
microcode: CPU7: patch_level=0x08701021
microcode: CPU8: patch_level=0x08701021
microcode: CPU9: patch_level=0x08701021
microcode: CPU10: patch_level=0x08701021
microcode: CPU11: patch_level=0x08701021
microcode: Microcode Update Driver: v2.2.

So my question is this: is early loading actually turned on? And if not, how would I go about doing it, exactly?

Run grub-mkconfig and post the output?

What CPU do you have?

If it's already up to date then no new microcode will be loaded.

Sorry about that, here it is:

It's in portuguese, but the translation is pretty much:

I have a Ryzen 5 3600, and my amd-ucode version is 20210716.b7c134f-1
