Can South Asian reference possible Native American ancestry?

That's just a noise.

Focus on your newly discovered Jewish ancestry instead.

Get a mtDNA test, you might be carrying Jewish maternal haplogroup which would make you legit Jewish.

No since you see some Finno_ural component there also you have NE Asia showing in other calculators that might indicate older Uralic/Dravidian Indian component present in many castes which some times show up Scottish_N in G25 nmonte for SOuth Asians. on Ged, Saamis have this kind of admix. I get >100 cM on 200SNP/2cM matches on Saami Kola samples & Russian Pinega ones
