Yes, you can modify my command to use "5.12.3-1-default". e.g.
/boot/initrd-5.12.3-1-default

Please still keep the original initrd file in /boot folder in case my modified
tables has problem because I do not have machine to test it. If the
instrumented_initrd-5.12.0-2-default has problem that it causes booting failed.
Then you just need to use grub2 UI to modify initrd back to original
initrd-5.12.3-1-default for booting.

Thanks
