AFAICT, there's no need for new images here - we just need to enable TPM support in our existing builds. I have this queued:
  https://salsa.debian.org/qemu-team/edk2/-/commit/3491bed29b4d9fd20b596987fbfa33a256185d02

The existing ARM images already have Secure Boot support. As for the 4MB aspect, AFAICT, ARM already defaults to the same size as x86:

OvmfPkg/VarStore.fdf.inc:
!if $(FD_SIZE_IN_KB) == 4096
  # Size: 0x40000 (gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableSize) -
  # 0x48 (size of EFI_FIRMWARE_VOLUME_HEADER) = 0x3ffb8

ArmVirtPkg/VarStore.fdf.inc:
  # Size: 0x40000 (gEfiMdeModulePkgTokenSpaceGuid.PcdFlashNvStorageVariableSize) -
  # 0x48 (size of EFI_FIRMWARE_VOLUME_HEADER) = 0x3ffb8
