Thank you.

Yes. You can follow the instructions to install and uninstall test packages
from that repository.

To install:

> zypper ar --repo https://download.opensuse.org/repositories/home:/michael-chang:/devel:/grub/openSUSE_Tumbleweed/home:michael-chang:devel:grub.repo
> zypper ref home_michael-chang_devel_grub 
> zypper dup --allow-vendor-change --from home_michael-chang_devel_grub

To uninstall (revert to official package)
> zypper rr home_michael-chang_devel_grub
> zypper ref
> zypper in --allow-downgrade  --allow-vendor-change --force grub2

Please note that you'll have to disable secure boot in UEFI firmware to test
the package since it was built in my home project thus not signed by openSUSE.
