update-initramfs failed - No /etc/kernel/pve-efiboot-uuids found

I am setting up a RAID on a new Proxmox 6.1 server and I wanted to update the kernel in order to keep the RAID after a reboot (I had to do that with Proxmox 5.x)

To begin, I created the RAID :
mdadm --create /dev/md3 --metadata=0.90 --level=1 --assume-clean --raid-devices=2 /dev/nvme0n1p4 /dev/nvme1n1p4
mdadm --detail --scan --verbose > /etc/mdadm.conf

After, I run update-initramfs :
update-initramfs -v -u

I got an error : "No /etc/kernel/pve-efiboot-uuids found, skipping ESP sync."

Available versions: 5.3.10-1-pve

Is this a good way to go? (Maybe is not necessary?)
Why do I have this error?

I dont see an error, just a piece of information ... on my dl360G7's i also see it when i update kernel ( the pve-efiboot-uuids - message) .. but never have i had any issues.

Thank you, it reassures me. Thanks
