Guess 5 days ago MSI pushed it to testing, run these commands on your variants and see if your vendors have pushed anything to testing:
sudo fwupdmgr enable-remote lvfs-testing
sudo fwupdmgr refresh
sudo fwupdmgr update
read the fine print - then just hit yes.
you’ll be on par with the founders edition after. if anything else gets tweaked before stable just run the usual:
sudo fwupdmgr refresh
sudo fwupdmgr get-updates
sudo fwupdmgr update
enjoy!
