Septentrio, Hemisphere and Trimble have boards capable of receiving NavIC/IRNSS, at least. The cheapest module would probably be Septentrio Mosaic-X5.

Digikey lists that module (which is not much different in size/shape from the U-Blox modules) at 675$, so I'm not sure this puts it in the cheap/hobbyist range ...
