Yeah, same issue here. A quick tip: try disabling Secure Boot, saving and exiting the BIOS, then going back in to re-enable it—that sometimes forces Windows to recognize it.

Agreed, that trick often works. Also, double-check that your BIOS is fully updated, as an older version can sometimes cause this mismatch.

Agreed. This happened to me on a different ASUS board. I had to go into the BIOS and manually set the OS type to "Windows UEFI mode" for it to finally be recognized.

You could also try clearing the TPM in your BIOS, as that can sometimes resolve the Secure Boot detection issue.

Yeah, Another option is to check if your BIOS has a "CSM" or Compatibility Support Module setting and make sure it's disabled, as that can interfere.
