I recently installed ubuntu 22.04 on a new Intel NUC. I created a Fat32 boot partition, and a pv for an LVM with mount points for root, etc, usr...et al. The install went fine and the machine boots. However, there appears to be two bootloaders. I don't know if that's an issue for how the machine works, but I can only modify one of the bootloaders to get rid of the timeout (appears to be the second one). When I look in EFI directory, I see a folder for ubuntu and one for boot - both have boot files in them, but only the ubuntu folder has grub.cfg. I hope this is making sense. Should I remove one of the bootloaders? If not, how do I make the timeouts on both of them zero? If reloading the OS is the answer, that's fine - I don't have a lot on the machine yet, but need to know how to do that without making the same mistake.
EDIT: As requested, output of efibootmgr -v
