Secure boot missing from BIOS on Lattepanda Alpha 864s m3-8100Y version KR300/KR310

Hi,

We have tens of lattepanda alpha 864(s) boards in use that are unable to update to Windows 11 25H2 due to missing Secure Boot. As far as hardware is concerned m3-8100Y should be compatible with Windows 11 25H2 otherwise. We are using the autopoweron BIOS from your GitHub on KR300/KR310 boards and there is no setting for Secure Boot anywhere, even though TPM 2.0 is available. There has been no updated BIOS release for 6 years now for these boards.

Is DFRobot looking to release an updated BIOS with Secure Boot support, or will all these devices now become obsolete in October (24H2 EOL) due to the lack of this single option?

Kind regards,

KM
