MMM BEC CHANGEABLE TO 6v or 7v

[BrianG]

Probably just a replacement/addition of feedback voltage divider resistors or something like that.

Someone should do this and take pictures of the PCB before and after. Then post a how-to...

Or, just disable the BEC and use a CCBEC like the old days. Aside from the added wiring inconvenience, a CCBEC would be about the same cost as the service.
