Just checked Win10 is 1909, when checking for an update says version 2004 is on its way
. Spent far too much time in testing, for now I just enjoy and that's it. Overall the culprit seems to be the bios
, will wait to see if better bios comes up in month or so, otherwise will be getting B550 Unify when comes available.
Found a way to manually update to the latest Win10 version if not offered from Windows Update.

ps. Looking for a good set of 32GB DDR4 to pair with the IF 2000.
