EM9191 Modem in Pepwave BR1 MAX Pro. Replaceable with an upgraded T-Mobile version?

Is it possible to upgrade the EM9191 modem that is currently installed in a Pepwave MAX BR1 Pro Cellular Gateway that is used on the T-Mobile Internet at Home Service? (Business account [BYOD] with static IPv4).

you better ask in peplink’s forum as the EM91 module is inside their router
