Netgear Nighthawk M6 Pro MR6500 MTU setting

[Blu4ce]

My company just purchased 4 of the Nighthawk M6 Pro routers for use on ATT FirstNet.  Our FirstNet APN requires a lower MTU than the standard 1500.  How do we change the MTU to 1428?  I don't see that option in the settings.

Thanks in advance!

Mike
