This shouldn't affect most users.

AMD has announced that its upcoming RX 9070 series (RDNA 4) GPUs will require a UEFI system for optimal compatibility. Put simply, it has dropped support for the older BIOS and CSM standards, requiring users to make the necessary shift to UEFI. While this doesn’t mean RDNA 4 GPUs will cease to function with legacy firmware, AMD offers no assurance.

    AFAIK, UEFI isn’t technically a requirement. However, TPM 2.0 is, and that requires UEFI.

    TPM 2.0 does not require UEFI. I have a system here with TPM 2.0 and only legacy boot support. And you can just buy a TPM 2.0 module and connect it with any board, that has a SPI connector.
