Support for EC200U-CNAA, EC200U-CNLA

Hi,
What is the difference between EC200U-CNAA and EC200U-CNLA? Can I use the QuecPython firmware of EC200U-CNLB on any of above modules?
Does QuecPython support the internal GNSS of EC200U modules?

EC200U-CNAA : 4G+2G
EC200U-CNLA : 4G
EC200U-CNAA and EC200U-CNLA do not support Python development.

Python support is available:
BG95:
BC25:
EC200U_CNLB( 8M):
EC200U_EUAB( 8M):
EC600U_CNLB( 8M):
EC600U_CNLC( 8M):
EC600U_EUAB( 8M):
EC600N_CNLA( 8M):
EC600N_CNLC(16M):
EC600N_CNLD(16M):

Does QuecPython support the internal GNSS and Dual-sim capability of EC200U modules?
