Yes, sounds a bit weired but you can use the downgrade tool to do this
Identify wich mesa and vulkan packages are installed on your system:
pacman -Q | grep mesa
pacman -Q | grep vulkan
upgrade all mesa and vulkan packages with downgrade:
sudo downgrade mesa mesa-* vulkan-*
hint:
needs to be the explicite package name (replace *) from first 2 commands.
And you have to re doing this step after a system upgrade so simply grep the last command again after system upgrade.
