Installing mesa-git dev channel (cutting edge) for open public test, to provide informations to the dev team.

I am on the latest Unstable branch of ChimeraOS and
I want to install the latest Mesa-Git from the developer channel (v25.2 = https://aur.archlinux.org/packages/mesa-git).
But I'm afraid to install it with 'yay -S' from the AUR repository.
Is this possible, or should I wait until the ChimeraOS developers provide an internal update process in the unstable ChimeraOS branch?

Thank you to all users for your effort and support <3

Note: I've tried every SteamOS fork, from the official Valve repository to CachyOS and Bazzite, but none of this installations worked on my GMKtec K8 mini PC*. Problem: I always get a black screen after the initialization process, when the installer has fully loaded, or after installing the operating system (I can hear the audio and USB, etc.). Only ChimeraOS working stable out of the box, but also with the unstable branch 🥇

* Systeminformation:
AMD Ryzen 7 8845HS
AMD Radeon 780M
32GB DDR5 (5600 MHz CL46)
ChimeraOS 49 Build (87bbea3)
Steam Build: 1748914100
BIOS NucBox K8 1.07

No files, tests, or entry points are named. First review the ChimeraOS unstable update and packaging process, then determine whether a supported Mesa-Git developer-channel installation path can be defined; done means the project documents or implements that process clearly.
