Looked online, but didn't find very useful info.
First machine has Fedora 43, and was a clean install to 42 on a
2TB drive with 16G ram.
Second machine has gone thru a number of upgrades.

duf shows slightly differrent
/sys/firmware/efi/efivars                 │ 384.0K │ 382.8K │    0B │
███████████████▌ 99.7% │ efivarfs │ efivarfs

First machine is brtfs for most partitions and second is ext4?

Not clear if this is a real filesystem, or something in ram?

Didn't find anything to resize it, some talked about gparted, and
some show using  but shows lots of stuff?
Machine has no Windows, or Floppy disk, or CD. Does have the
nvme 2T disk, and does have NIC.
Not sure why the size would be set to 384K?

It's not a partition or a real filesystem, it's the UEFI nvram storage and if it gets too full, it can cause problems. I've seen a reference to dump files that might need to be removed from there.

You could also try factory reset in the BIOS. This will probably remove the Fedora boot entry, but that will be automatically fixed when you try to boot from the hard drive.
