I have figured out how to get the Dyn. Relocs Table with which we can get the alternate export directory from an image on disk:

			IMAGE_LOAD_CONFIG_DIRECTORY64 LoadConfig;

			IMAGE_DATA_DIRECTORY* dir10 = &opt_hdr_64->DataDirectory[IMAGE_DIRECTORY_ENTRY_LOAD_CONFIG];
			if (resolve_ec && dir10->VirtualAddress && dir10->Size >= FIELD_OFFSET(IMAGE_LOAD_CONFIG_DIRECTORY64, CHPEMetadataPointer) + sizeof(ULONGLONG)) {

				status = ReadDll(hProcess, FindImagePosition(dir10->VirtualAddress, nt_hdrs_64, DllBase), &LoadConfig, min(sizeof(LoadConfig), dir10->Size), NULL);
			}

			typedef struct _DYN_RELOC_TABLE {
				ULONG Unknown1;
				ULONG Unknown2;
				ULONG Unknown3;
				ULONG Unknown4;
				ULONG TableSize;
				UCHAR Entries[];
			} DYN_RELOC_TABLE;
			
			DYN_RELOC_TABLE* DynamicValueRelocTable = NULL;

			if (DllBase == 0 && (resolve_ec || resolve_exp)) { // only for images on disk, on linve images we take the actuallly used export directory

				PIMAGE_SECTION_HEADER section = IMAGE_FIRST_SECTION(nt_hdrs);
				nt_hdrs->FileHeader.NumberOfSections;

				section += (LoadConfig.DynamicValueRelocTableSection - 1);

				ULONG pos = FindImagePosition(section->VirtualAddress, nt_hdrs_64, DllBase);
				status = ReadDll(hProcess, pos, Buffer2, min(sizeof(Buffer2), section->Misc.VirtualSize), NULL);

				DynamicValueRelocTable = (DYN_RELOC_TABLE*)(Buffer2 + LoadConfig.DynamicValueRelocTableOffset);

				//dir0->VirtualAddress = 0x308810;
			}

			for (UCHAR* TablePtr = DynamicValueRelocTable->Entries; TablePtr < DynamicValueRelocTable->Entries + DynamicValueRelocTable->TableSize; ) {

				struct {
					ULONG Offset;
					ULONG Size;
				} *Section = TablePtr;
				TablePtr += 8;
				Section->Size -= 8;

				for (UCHAR* EntryPtr = TablePtr; TablePtr < EntryPtr + Section->Size; ) {
					struct {
						USHORT  
							RVA : 12,
							Unknown: 1,
							Size : 3;
					} *Entry = TablePtr;
					TablePtr += 2;

					ULONGLONG Value = 0;
					memcpy(&Value, TablePtr, Entry->Size);
					TablePtr += Entry->Size;

					DbgPrintf("%08x -> %08x\n", Section->Offset + Entry->RVA, (ULONG)Value);

				}
			}

there are a couple unknown values so if anyone has an idea what they are please share.
