Do not know for sure, but Windows 8 was the first with UEFI Secure Boot.
Many UEFI/BIOS have setting that says "Windows" or "Other", others have UEFI Secure Boot on or off.
The one's using "Other" type setting have fine print somewhere that says if booting Windows 7 in UEFI mode, use "Other". Windows 7 does not support UEFI Secure Boot that started with Windows 8 in 2012.
I have seen a lot of reasons to just update UEFI. Not specifically your model. But a couple of examples on why you typically do want to update.
Last year AMD put out a fix that was required for Linux to work. But motherboard vendors had to push out new UEFI updates with that fix.

ASUS ROG CROSSHAIR VIII HERO WiFi - update supports Ubuntu 19.04
MSI has also put out BIOS updates in Aug as a "beta" though without explicitly acknowledging the Linux fix.
This would not apply to your older cpu, as it does not speculate.
And almost all newer cpu including your Raspberry Pi and IBM mainframe that speculate on what next bit of code will be and load it into RAM before needing it, have needed UEFI updates. And Both Linux & Windows updated operating systems, also.
Almost all systems need UEFI updates, anyway, for mitigation of Meltdown and Spectre CPU vulnerabilities from cpu speculative execution and caching.
Ubuntu 18.04 LTS has the Linux 4.15 kernel, GNOME Shell 3.29.1, Mesa 18.0-rc5, GCC 7.3.0, Python 2.7.15rc1, Python 3.6.5, and is mitigated for Meltdown with KPTI while for Spectre V1 it opts for __user pointer sanitization over OSB and for Spectre V2 has full Retpolines.
Or there are a lot of things in background going on, and not everyone knows all the details.
