RIF and DE cycles

I have had 5 DE failed cycles. I’m Kir-Aa, I have Hashimotos, and I’ve been on Lovenox, Prednisone and Aspirin for the last 3 rounds and still failed despite high quality embryos. The donor was HLA. Now we can start again with same or different donor and I was told to try intralipids infusion. Are they missing anything else?
