os-prober will not be executed to detect other bootable partitions

Just did an update of my Proxmox 7.4.17 and After That I am getting this error

Warning: os-prober will not be executed to detect other bootable partitions.
Systems on them will not be added to the GRUB boot configuration.
Check GRUB_DISABLE_OS_PROBER documentation entry.
Adding boot menu entry for UEFI Firmware Settings ..

Is it Ok ?
Can I reboot the System to update the kernel?
