Can I upgrade from a 240V 30A circuit to a 240V 50A circuit?
I have a new range with a NEMA 14-50P plug. I find my 240V receptacle is for a dryer, with the top blade a 90° one. So I need to change the receptacle out.

Adding GFCI to a 240v outlet - Home Improvement Stack Exchange
Most residential circuits are 120v only. Most residential 240v-capable outlets are actually 120/240 and have a neutral to provide the 120v service. But your L6-30 (Or any 6- for that matter) is not capable of providing for 120v devices, and this means your load doesn't use neutral. So its GFCI protector doesn't need access to neutral either.
