According to its Datasheet (https://dfimg.dfrobot.com/nobody/wiki/afe407bbc2add6b9ba8a1014dbb82d26.pdf), this module, the L76, supports SBAS: WAAS, EGNOS, MSAS, GAGAN, but in its library, it is not possible to capture HDOP, VDOP, GDOP, PDOP, etc. The main issue for your customers is that you present a Datasheet of a product that is not correct, TEL0157 solders a Quectel L76K module not the L76. Both modules are completely different:

 

L76K: Chip: AT6558R / GNSS: GPS / GLONASS / BDS / QZSS

L76: Chip: MT333 / GNSS: GPS / GLONASS / Galileo / BDS / QZSS

 

If the L76K module indeed supports SBAS, you must implement dilution in your library: HDOP, VDOP, GDOP, PDOP. I kindly request you to make these modifications to align with the information you provide. Thank you.

The chip used on the TEL0157 should be L76K not L76.

The L76K doesn't seem to include an L1 band for SBAS. Consequently, the library might struggle to display error settings such as HDOP, VDOP, GDOP etc.

maybe it would be good to submit a GitHub PR/ issue.
