Linux-drm-tip from AUR

Hi there ! I would like to ask the linux-drm-tip from AUR, or if it isn’t possible, can you give me points on how to install it correctly from source, many thanks.

The PKGBUILD for linux-drm-tip from AUR has some different structure to the Manjaro kernels PKGBUILD, hence why I’m asking for an approach for the drm-tip kernel installation not necessarily the exact linux-drm-tip from the AUR, thanks.
