Aditional skins for nightly builds?

Is there a way to get more skins than the two I see in the menu system?
If I select the ‘Get More’ option only Aeon Nox and Arctic are available for download, no others.
Is there another repository I need to add, or are their no other options at this time for nightlies?
I am currently using CoreELEC-Amlogic-ng.arm-21.0-Omega_nightly_20240126-Odroid_N2.img

You can install kodinerds repo, there you van choose is the estuary mod v2, which ready for newest omega too and has tons of features.
