Done. Still the same "System uptime in nanoseconds".
Also entered all the following commands :

sudo rm -f /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache
sudo touch /System/Library/Extensions
sudo kextcache -i /
sudo nvram -c
sudo purge
sleep 1


And I still get the error "nvram: Error clearing firmware variables: (iokit/common) not permitted"

Messing around with the cache will have no effect on a spurious KP in NVRAM.

Still the error after entering
$sudo mount -uw / (OK)
$sudo nvram -c
nvram: Error clearing firmware variables: (iokit/common) not permitted


Should I remove EmuVariable64.efi ? (like this thread)
Thank you for your help ! :)

Should I change my default loader from boot.efi to BOOTX64.efi in Clover configurator ?
I am lost...

Your problem lies with NVRAM, I don't see how changing the default loader will impact on that.

OK... Is there anything more I can do with this nvram?

To be clear, your board does not have native support for NVRAM and it is the emulation of it that is the problem.
You have a spurious kernel panic stored in the emulation of NVRAM which you must clear in order to remove it.

OK. Do you have any idea on how could I do this?
