Interestingly, there seems to be another github area from
solidrun referenced by:

https://developer.solid-run.com/knowledge-base/lx2160a-firmware/

that has a link that points to:

https://github.com/SolidRun/lx2160a_build/tree/LSDK-19.09-sr-uefi

Note that it is explicitly uefi . There also is a non-uefi branch:

https://github.com/SolidRun/lx2160a_build/tree/LSDK-19.09-sr

The referencing developer.solid-run page says:

Currently recommend are branch LSDK-19.09-sr for U-Boot, and branch LSDK-19.09-sr-uefi for UEFI!

However, the notes on the developer.solidrun page referenced
say:

QUOTE
Binaries

At this point in time we do not provide firmware binaries due to the necessity of deployment-specific configuration. While we are working on simplifying this situation, firmware can be compiled using our tool linked above, and explicitly taking into account the particular RAM installed on the system, as well as the intended firmware media (SPI, microSD, ...).
END QUOTE

But:

https://developer.solid-run.com/knowledge-base/honeycomb-clearfog-cx-installation-and-tips/

does reference a pre-built image. But it is not explicit upfront
if it is the uefi variant or not.

One hint may be other text on the page and what that text
references:

QUOTE
To flash to eMMC run the following commands (it will wipre your data on the eMMC device). For this to work eMMC distroboot support is required (patch is here – https://github.com/SolidRun/lx2160a_build/commit/75891e5cb4d2171a2094c1e35087374b1f47acdd )
END QUOTE

and that patch area has things like:

patches/{u-boot → u-boot-LSDK-19.06}/0001-armv8-add-lx2160acex7-build-inclusion.patch

This suggests it is the example is u-boot material,
not uefi material.
