How to use Valve ACO Mesa Driver on Manjaro?

Currently, I'm using Mesa from mhwd. I would like to switch to using Valve's ACO Mesa driver for improved game performance. A handful of the games in my library benefit from ACO that I know of, so I want to switch from using mhwd-mesa to using what I believe is mesa-git, which installs as a dependency of mesa-aco-git (amongst other things such as llvm-git). What is the best way go to about removing the mhwd mesa and installing mesa-aco-git (and lib32-mess-aco-git by extension)? Will this also remove my lib32-mesa package? I am unsure whether or not this installed as part of mhwd. I read another thread, but it was almost three years old at this point and said something about keeping mhwd due to dependencies. Fiddling with drivers - especially core ones like graphics drivers - can be a little scary, and I want to make sure I have the lowest possible chance of hecking it up.

So in short, what's the cleanest way to install mesa-aco-git and lib32-mesa-aco-git on Manjaro Linux?

Thanks!

Be warned that installing a development package like this could at best be buggy and at worst break things.

An AUR helper like pamac or yay will handle everything for you. Here's a preview:

Worked like a charm! Thanks! Everything seems fine for now, for what it's worth, but as you said definitely worth keeping in mind that development drivers can always be unstable! Great stuff, thanks!
