Can you "grow" a human from 2 sets of same sex parent DNA? (lemm.ee)

Idk if this makes sense.

Obviously not via sexual reproduction but could a person's genetic parents be of the same sex and that person be genetically indistinguishable from the rest of the population?

To vastly oversimplify how genetics and embryonic development works, the "default" for humans is female and men have genetic codes that overwrites these defaults during fetal development. To put it more bluntly, males have extra code which females lack.

That could explain why sperm+sperm could theoretically work using a stem cell as a mediator to remove the excess code, while egg+egg can't do the same because you'd need to manually scribe the extra genes directly.
