That's an early build, maybe Windows 11 RTM will actually always use a TPM (1.2 is advertised as minimally supported though). As for secure boot, I don't see how that could be anything else than policy (that can have an impact on a security model and so on associated security measures, granted, but not having secure boot should technically not prevent booting / installation unless it is enforced by an explicit artificial limitation). But they could at least remove legacy boot support, in which case it just won't work without UEFI.
