cp -ax /boot/grub2/grub.cfg /boot/grub2/grub.cfg.orig-$(date +%s)

OR

# For "/boot/efi/EFI/centos/grub.cfg"
cp -ax /boot/efi/EFI/centos/grub.cfg /boot/efi/EFI/centos/grub.cfg.$(date +%s)

OR

# For "/boot/efi/EFI/almalinux/grub.cfg"
cp -ax /boot/efi/EFI/almalinux/grub.cfg /boot/efi/EFI/almalinux/grub.cfg.$(date +%s)
