(I have the same issue)
Asus Z590 Plus wifi
Intel 11700K CPU

Step 0: Download PC Health Check from windows website
Step 1: First upgrade the Bios with EZ-Updater from the Armory tool set
Step 2: Set bios to TPM 2.0 using the bios search page top center.
Step 3: Set bios UEFI to windows or other ( different forums tell use one or the other ) using the bios search page top center.
reboot should work but See Pic 1 )
Then I checked MSinfo ( See Pic 2 ) its still in legacy mode and safe boot not avail
