How to modify Here3 GPS Constellations to GPS+Galileo+GLONASS+QZSS?


I am getting low number of satellites in Here3 GPS 12-14 while Here2 GPS has sats 16-22.
I wanna modify GNSS Constellations in Here3.

I have read the Cubepilot Document about how to change GNSS Constellations in

BUT , there are only three options
gnssConfig = 8 for BeiDou
gnssConfig = 9 for GPS+BeiDou
gnssConfig = 97 for GPS+GLONASS+QZSS
I wanna change it to GPS+GLONASS+QZSS+Galileo+BeiDou

Kindly help which value of gnssConfig to set for the above config?

Would be nice to have more options, than those 3 options. I would like to use GPS+GLONASS+Galileo

As i have read in the docs of M8P , there are only two concurrent GNSS Systems that can be selected ., is it right??

Yes. And use appropriate update rate from below!
