I don't dare mess around with the UEFI settings just yet but are there any commands/applications that will reveal what is stored in NVRAM?

As Colin said, use efibootmgr. Also see
<https://linuxconfig.org/how-to-manage-efi-boot-manager-entries-on-linux>
and <https://wiki.gentoo.org/wiki/Efibootmgr>. (Ubuntu does not seem
to have a specific page for efibootmgr).

Probably.
