The Alder Lake N CPUs have in-band ECC memory controllers, because they are also sold as Atom CPUs for industrial applications.
I do not know if the IBECC controller is functional in all models, but it is usable at least in the models that are marked by Intel (in Intel Ark) as suitable for embedded use, like N97 and i3-N305.
The IBECC controller requires BIOS support. Among the computers known to have BIOS support for IBECC is ODROID H4/H4+/H4 Ultra (the 3 models differ in the CPU model or the number of Ethernet ports and SATA support).
IBECC works with non-ECC DDR5 or LPDDR5 memories, but it reduces the available memory capacity and performance in comparison with traditional ECC. Because no memory vendor offers LPDDR memory with ECC, IBECC is the only way to implement ECC in the CPUs like Alder Lake N or Amston Lake, which are intended to be used with LPDDR5 memory.
