No, you cannot use pflash for CODE in either SNP or TDX. The hardware does not support it. One possibility is to only support non-pflash-based variable store. This is not yet in QEMU, but it is how both AWS and Google implemented UEFI variables and I think Gerd was going to work on it for QEMU. Paolo
