TAIP GPS Need To Use LN Sentence

I will be soon testing the BR1 Mini HW3 GPS forwarding for our city 911 dispatch. They use TAIP GPS LN (Long Navigation) sentences.
I do not see that as an option, would I just check both boxes to achieve that? (fixed typo)

Digging deeper it looks like having both checked doesn’t really help much.
Does anyone know how to send LN sentences from the BR1 HW3??
Any assistance would be greatly appreciated.

Peplink Engineers??

Did you ever get any insight on this? Looking to switch over to peplink from a different modem vendor but need TAIP LN messages not just TAIP.
