EDIT: I see that SRAM Rival 1x crank specs list 38t as the smallest chainring. (And this crank is 110 BCD 5 arm)
I don't know if that is because the smaller rings from Wolf don't actually fit, or if SRAM just doesn't make a 5 bolt 110 BCD ring smaller than 38t.

Probably the latter. I was thinking of the 38t limitation with road 130bcd cranks, but I think you can physically go down to something like 30t on 110.
I bet 38t would be a good compromise, however. Going lower really starts hampering you high gear in a 1x with an 11t cog.
