On the off chance that this issue has a broader impact I will leave a reference to https://answers.launchpad.net/ubuntu/+question/708251 wherein similar behaviours are being observed with 6.5.0-9-generic on amd64.
efivar -l returns: "efivar: error listing variables: Function not implemented", yet `ls /sys/firmware/efi` returns entries.
I noticed this after upgrading from Ubuntu 23.04 when efibootmgr stopped working.
Ubuntu 23.10 x86_64, 6.5.0-9-generic (Plasma 5.27.8 if that makes a difference).
